Great time my wife took me for my birthday party. We had a private room for a few of us and a lot of races. All the food very good. The carts were actually faster than I thought They can really move!

What a great time did this for our Holiday work party. I cant thing of a better way to celebrate. Staff was super courteous and accommodating. We will definitely be back.

This place is the real deal. The karts go fast, and handle very well. The systems were accurate and detailed, and I liked how they track your laps from previous races. Overall it was an affordable trip that I can definitely see myself doing again!

Loved this experience. A great staff walked us through the training and the process. There’s a bar upstairs (but you can’t drink & race) which is a great hangout between heats.The carts were quick and the track was challenging, but fun. Although you’ll get called out for reckless behavior they did let some contact go (“Rubbing is Racing”).The staff kept things moving and we never felt like we were waiting around between heats.

Had a super great time at Unser Karting! I planned a birthday party for my boyfriend and several of our friends. Kyle, our event coordinator did a great job hyping us up, bringing us food and drinks, and getting us on the track at the right time for each of our races. Everyone had a blast and we are looking forward to coming back!!

Love this place! Great people and service as always! Thank you for keeping entertainment alive during these times

Not family friendly.Took my wife here for her B day as a surprise. Our group was matched with people who had their own helmets, gloves....took racing pretty serious. When they rammed my wife 3x on our first race I thought that wasnt cool, but if it got out of control the managing kids might get involved as they said they would in the safety talk. Well...not the case. I would never take a child here, I would be hard pressed to ever go here again. I have raced many places where they took car to car contact serious and even at much lower speeds. Not here. If you want to do crash up derby, maybe the place for you. If you want to have a happy birthday and experience family fun racing, I would suggest one of the other racing clubs in town. Myself, my wife, my son, and a younger friend we brought with us to celebrate all share this sentiment.

Just went to Unser for my wifes birthday, thought it was going to be a great time. After the safety talk I thought everyone understood it was for fun. Well....was I ever wrong. They had us race 3 races with a group of people who thought this was some sort of Indy tryout. After my wife had been intentionally hit multiple times the first race I thought she may just be sensitive. Nope, and the managing teenagers must have thought it was acceptable as they allowed it to escilate to intentionally ramming everyone in our party. One visit was enough for me here. I wont be back and would never allow a child to go here. Safety nor fun are paramount here.

Very organized place. They explain everything thats pretty simple for first time being there. Staff very helpful to answer questions and help you as needed. Staff are on top top of things during race. Over all a must done prepare Togo fast. Not your average slow cars

Pretty awesome fun date place or with friends. Kind of pricey but can find deals on Groupon. Karts so at least up to 30-40mi/hr. Pretty fast speed to unleash your inner rage and be competitive! Super clean an cautious also.

Went there for the first time this past weekend, and it was super fun. We are definitely going back soon.They sanitize everything very well, and things are very well organized. Staff are super friendly and helpful.

Fantastic! Worth every penny. Karts are FAST! Went with a small group from work and we had a blast. Food and drinks are well priced and tasty. Definitely plan a trip with a group of friends and co-workers!

This place is awesome! If you have an itch to burn rubber, this is your outlet. The staff here are very chill and went to make sure youre having a good time. They also want to make sure everybody is safe. The bigger your party, the better!

Ive been here twice and my friends and I really enjoyed our time!Expect to wait about 30 min before you actually start racing and that will vary on how many people are there (you will have to go through training and once thats done you will wait for your group# to be called). They have a pretty organized system though.I believe they have discount days, go check it out.Reservations can be annoying because you have to be sure that everyone in your group is going as you have to pay for the entire group the moment you make the reservation and if someone doesnt come through they dont do refunds. Also, make sure to check their website or call for details/info especially if youre thinking of bringing younger kids as there are additional things needed.These karts go fast so you can get hurt if you bump into things or someone which they will warn you not to do!At the end of the day, we all had fun here! Recommend to try at least once!

Fun times! Staff is friendly and definitely makes your event more fun!

I have been coming to Unser for years, it is never a let down. The prices are a bit high but it is still a blast. It is great for bonding with friends and family.

Was really fun. Track and carts were great. A little confusing first time around, but was able to figure it out as you go. Would recommend for anybody!

3 races, 3 huge blasts of adrenaline!!!! The staff made this place even better! So much fun racing here.

Staff was not very helpful or accommodating. We had a big group and getting everyone registered was a pain. They’re not really interested in earning our business so we gladly took our money elsewhere. Not impressed.

I spun out on the track and someone hit me from the side. These karts go up to 50mph mind you. I got slammed into the barrier and my helmet flew off. My nose was bleeding and I sprained my ankle. The guy who i assume was the manager wasnt too helpful. I really thought there would be an ambulance there or a medic on site but there was nothing. I was only offered a bag of ice. Very poor way to treat someone shaken up and injured. I also asked multiple times before walking off the track to let my friends know which they didnt. I am in lots of pain. Needless to say ill never be back.

Always good fun whenever I get the chance to go here. A little pricey in my opinion but for most it is worth it.

Got 11 best time of the day awesome place to race with friends Im definitely going back

Super fun go-kart track. Definitely recommend!

Great racing track! Such a fun place for parties or work events

Really fun spot. Great spot for a large bachelor party. They keep things moving quite fast

I love this place didnt charge an arm & a leg to have fun. The employees and managers were amazing as well. A must to visit while in Colorado!!

Really nice kart racing and is super interactive with kids

Great to do as a group. Took the family and had a great time

This place is amazing. Great and Polite staff with awesome customer service.

A bit pricey but a lot of fun, great for work get togethers

Great facility. Staff was friendly and helpful. About an hour wait, but nice gameroom and restaurant to relax in.

This place is totally cool. I love how they were with my 6 year old. The carts, the tracks, the overall experience was really good. The bar with food is top shelf too. How they do that and still turn a profit I dont know, must be a lot of volume. The costs is actually very reasonable for what you get.Solid operation, great equipment, the people are really cool and take their work very seriously while being courteous, professional, and safety conscious.This would be a great place for a birthday party, in fact I am planning one there next month.

WOW What a Great time.Thank You Credit Safe for inviting us.KYLE U ROCK you and all the staff were Great.This is a A 1 place to have fun.Pool tables

Thrilling ride, addicting experience. Highly recommend!

So much fun highly recommend it. Will be come back !

Friend recommended this place and it turned out awesome. Had a deal with 4 races. Carts are fun and track is technical and a fun layout

Went for a work party. Very fun. Nice staff and the food was actually pretty good too. Mozzarella sticks very crispy. Not sure on prices but fun factor was a 10/10

Very fun place to go for dates, family events or just for a fun outing. Its on the pricey side with individual pricing for a 5 minute race running $19 - $25 depending on the day. Definitely lots of fun worth going at least once.

This place makes scheduling reservations absolutely ridiculous. Can’t make reservations for small groups and even when you have a group big enough there is never enough room. So if you want to have fun here I would recommend setting a reservation a year in advance. Thanks for nothing Unser Racing I hate you.

SUPER FUN!!! Me and my boyfriend went there last month and had a blast! I admit, I was really nervous when I first got out there. But once we started racing, I enjoyed every minute of it. Definitely recommend checking out Unser next time your in town!!

We love this place however you can tell that business is slowing way down. Used to be well to wall people on the weekends now you can race multiple times without hardly waiting. Hope they can figure out a way to keep it going. Racing is fun for all ages 6 and up, food is good, beer is always cold and the staff is always friendly.

Great facility. Parking. Free lockers. They had a bar, batting cages, a game room with pool and ping pong. Wish they offered a vegan selection on their menu, or some healthy choice of food. We raced twice and the karts are in great condition. The track is super fun and my husband got 1st place in his heat!!

This was the most legit go kart spot Ive ever been to. It happened to be on a day where the Rooftop track is open so got some cool views Denver. Workers super friendly and made us feel comfortable even though it was our first time. They provide you with head covers for the helmets when you get in. You are instructed of basic safety and guides. You then take the elevator up to the roof. You are assigned certain heaps and they will tell you when it is your turn. The cars are gas. They are pretty quick although the track does have a lot of turns so you cant really acheive top speed with the exception of the overpass, yes overpass. Super cool spot would go back.

Oh my!! Had sooo much fun! Went for a birthday. Kind of expensive, so will be a while before I go back but will definitely go back. Great for special occasions!!

Booked a small company Christmas party. Everyone had a super fun time and they all voted to do the same event next year. I want to give a shout out to Benson who was exceptional in working with me to get everything finalized and coordinated. Thank you Unser Racing for a great team building event for our company.

Best go Karting I have ever done. Powerful and well-designed karts. Other equipment in OK shape, including helmets, neck rings, suits. Some other pretty cool things to do in the arcade too. Great group rates.

I love racing here. He go carts are pretty quick and they are fun to smash around the course. Good place to be social and enjoy a night with friends.

Expensive but fun. I, like a few other people in my party, thought this was a stupid idea as something to do. We were proven wrong in the best way. Once you get on the track it is a blast. Fun environment if you group is even a little competitive. It is over quick though. Gets expensive real fast in you break it down as amount spent per minute

It takes a while to get this going....safety video...get on your super quick racing suit....but fun. Drinks and food bar there too

The only thing I didnt like was the a guy with a sign. The rules didnt seem to be the same for everyone. The kids racing with us didnt get flagged for the same things we did. Other than that it was a pretty good time. The bar at the end was super fun!

Roof Worx had another great event with our friends at American Roofing Supply. Great racing, good food and everyone had fun.

So much fun! A little pricey but so worth it! Great experience you will not want it to end

Very well kept place and lots of fun. A little expensive in my opinion but its all worth it. The only reason Im not giving it 5/5 was that one of the GoKarts I used had extremely lose steering and I would lose control and spin out. On the third spin out the race master gave me some smart-Alec comment about turning with a massive RBF going on. Even though its not related to the place itself that is still not acceptable in my opinion for a place of work where you are responsible for the safety and well-being of all of the racers who drive at 30+ mph and could possibly get hurt.

Awesome experience-this was a company event. If youre tall, the karts are a tight squeeze but still a thrill. Once done, the bar is well stocked if thats your thing.

Incredibly impressed with this place. Would highly recommend for company outings / team building events. Very professional and personable staff, and the whole event was incredibly well-organized. Thank you!

We had a company event here which was a great time, and we received wonderful customer service. Unfortunately, the caterer we selected through Unser accidentally left out one of our sides so when I told Becka, our event leader, she immediately informed her manager, Taylor, who gladly went above and beyond to take care of the issue right away. Becka was very kind, personable, and helpful the entire time outside of this hiccup as well.

Super friendly staff. Great place for work meeting and activities

Extremely homophobic, nationalists, as a Serbian immigrant I felt extremely profiled because of my accent, because of which I decided not to race and asked for a refund, and even then they refused to accept that idea

I had a blast when I went. This is the first place Ive been to that appropriately uses blue flags. The track layout is fun and easy to learn. If you have trouble getting fast times you can study the track map they give you with the preferred racing line, the braking points, and apex of turns.Not all karts are equal here. For example #40 had really tight steering; as opposed to #47 that had loose steering and took more than double the input to turn.I was pretty sore where my shoulder blades met the seat. The next morning I had pretty decent bruising across my back that is very sore. If youre skinny there will probably be some wiggle room in the seat even with everything tightened down. Wearing something with a little padding under the suit should help prevent getting beat up and bruised.Overall I had an awesome time. Ill definitely be heading back regularly. Just with a little more between me and the seat.

I had the need for speed

Started my bachelor party here and it was a blast. Much more intense than we thought it would be at and a lot of fun!

Took my son and a couple of his friends to do the Jr. racing Sunday morning. The Unser team is about safety which is good. They loved it. It is good for a rare occassion but is very pricey.

Went for a private event. Food was okay, bowling lanes were not working. I would have preferred electric carts to avoid the noise, smell and hot surfaces. The track was layout was fun with some challenges. Watch out for the huge bump before the last turn, killed my back.

Best go kart place Ive been to. The course is great and so are the karts!

Pretty freaking fun. I guarantee the times are not correct, and the pricing is way high. But zoom zoom!

I love this place

Company function, great place for competitive fun. They manage the races well, and have fun with you.

Great time at a company function. Karts are very fast and staff is friendly. Place is clean and comfortable.

Seriously the most fun Ive ever had. The carts go 50mph!!. My adrenaline was jacked

Super fun track. Fast carts. Nice staff. We had a 930pm race which got delayed an hour because someone crashed into a barrier. Nobody’s fault obviously but we found ourselves sitting in a bar until almost 1030. They cannot serve alcohol until your done racing. Once we finished the bar was closed because it was so late.

The ventilation is so poor that both myself and two others in our party ended up throwing up due to gasoline vapor inhalation. When I brought it up there was little sympathy rather excuses from the manager on duty. I wouldn’t recons coming here, the service is rude and lacking on all levels based on this experience. This place is focused more on the dollar then the customer experience.

It was awesome company event had the whole place to ourselves had several races around the track

Husband and I were looking for something new to do. It was a blast. Definitely will be back.

It was very fun but they did not give enough direction and they didnt check if our seatbelts were on correctly they were not as sage as i would like but overall it was a great experience.

Fun track. Awesome time!

For a rental karting biz, this location was above average. Orientation was brief and had realistic expectations of the drivers. The optional and free to use driver suits and neck braces were clean, balaclavas are yours to keep. The course flaggers didnt overstep except after really egregious bumping. They have karts with hand controls too! And the 6 different karts I drove all felt consistent and others in my group felt the same, the karts were equal. They put some thought and effort into this place.

Most fun I have had in a long time!!!

Our company came here for a team builder and we all had so much fun! Ive been to a lot of other karting places locally and out of state and this one definitely has it all figured out. The karts are pretty fast too! Highly recommend.

Excellent billboard marketing.

Awesome place to race carts no matter the skill level

Super fun!

It was a lot of fun . And the carts go fast. But the track is small and there are very very few places to pass. I am 6 foot and 300 lbs so the carts are a little uncomfortable but they definitely go fast enough for the track.

Great place for company morale events / team off-sites, as well as for the kids on a Saturday morning.

Really fun afternoon. The track is detailed and intense. The karts are fast and the staff is fun.

I do not agree with how they will throw you in big heats with other inexperienced drivers. I had one such driver who would not let me pass and would slam his brakes making it unavoidable for me to make contact. I was then treated like I was a villain, getting multiple flags and bad looks from the staff. After the race I got cussed out by this poor driving individual and his family IN FRONT of the staff. The staff did nothing. I have been here half a dozen times and these shortfalls are always common themes. Word to management: Let experienced drivers have their own heats, take better care that every kart preforms the same, and when people will not let others pass, black flag THEM. Until then I say dont waste your money if you want to be competitive in any way.

Love this place but it seems that they have forgotten this is a place for lap times. Flags mean nothing and races get waisted every time I go. They really need to keep up on the maintenance on the karts. I’ve been going for years and the karts always having something wrong with them. Worn no longer flat tires,steering is a mess, and brakes are horrible on at least one of the races

First race was fine, second race on Car #1 was . Told the manager about it... did nothing. Careful with defective cars

They require a picture ID to drive their cars on an inside track.Then they have your information permanently.Who knows what safeguards they have in place to protect your private information.I mean, why do you need a photo ID to ride a go-cart indoors? Makes no sense.

Always fun, always first! Had a great time every time!

Too much fun

This place is a BLAST!!! It is pricey, but I am sure the overhead costs are not light either! The carts are very well-maintained! The staff is great! The more fun you are having, the more fun the staff gets!

Place is easy to locate and near interstate.lap is little short as each lap is about 30 to 40 seconds for each lap. Carts performance is good, clean burning, so the after racing you wont smell too horrible with gasoline smell.They also have batting cages, pool table,ping pong, Foosball, and mini bowling available, may require extra fees.Extra noteDuring 2017 Dec 20th visit, the pool sticks are bad and tips are missing, one of the 2 pool table has damaged cushion. I advised the staff and hope they will get that resolve soon. (I understand pool is not their main attraction, but since I have to pay to play, I consider the condition not acceptable)

Such a cool place. Friendly staff, fast go karts, pretty solid briefing for safety. Go to their website and sign up for the newsletter, they give you a free race for doing so.

Last time i come here... i brought a friend it was Saturday and i understand that Saturday’s are more expensive however the race times are short even with the higher price. My friend spent over $40 for 1 race aka 5 min. Also the kart i was in leaked gas all over my clothes. I understand you want to make money but you can’t keep raising prices and decreasing race times. Expand adding more tracks don’t push your customers away from nickeling and diming them. I know there are other options in Denver they will be getting my business from here on out!

A little pricey but the cars are fast and well-maintained

Great place to bring your most competitive friends and family to prove who is the fastest. The track is laid out with a good variety of left and right turns, from tight hairpins, long sweepers, to tight chicanes. The karts are not that fast but are certainly faster than the track. Track staff keep the racing fun for everyone by directing slower traffic or out of control drivers accordingly. This helps to make the facility great for families with kids as young as 4, or a bunch of washed up car guys that still claim they could beat anyone.

Great environment would def love to do it again

Way fun! Went here for a company Xmas party, I was apprehensive about it at first but really glad I went, it was very very cool. The staff really did a fantastic job (gosh, I wish I remembered her name, shes the assistant manager and was our group leader, big kudos to her), there was a little training course that was very helpful, and then we did a Grand Prix race and finished with food and beverage. Cant drink alcohol before you go on the track, which is perfectly reasonable. Remember to pick something cool for your racer name when you sign in at the desk, I didnt realize it was going to be your display name and that you could do something silly. Anyways, it was way fun, totally recommend for a group event, I could see my brother and a group of his friends doing that for a birthday party.

One hell of a good time went with 12 or so guys for a work party and it was a great time the food was aslo very good definitely highly recommended

A lot of fun. I wanted to keep going after the two races. If going in the Winter time, I definitely recommend leveraging the free gloves they offer before going onto the track because my hands felt frozen after the first race. Great team building event.
