Not that there was any issues, but it can be overwhelming On the other hand, there was an unruly father who would not take no for an answer. Santiago had to get the manager and security because some dad was arguing with the poor employee about not letting his son go on a ride because he was too short. The manager came with security two separate times and he still would not listen. Thanks Bullwinkles , thank you for keeping us safe!

My wife, son and I recently visited Bullwinkle's in Upland for the first time and our experience…read morewasn't that great. We had taken our son to go use the batting cages and when we got to the counter there wasn't anyone to assist us with getting a bat or hat. We waited a good 10 minutes and when we noticed the person who was supposed to help us was out there batting while he was working. I had to go to the front counter to go complain because it wasn't fair for us to be waiting so long. Another thing that we didn't like was if you have Schools first debit card for some reason they couldn't take it. The good thing was we had cash with us, but if we didn't we were going to be screwed. All I got to say is they have to work better with customer service.

We ordered food and had seating in a private room as there were 30 of us. For the race you're not allowed to intentionally bump others to get a lead otherwise the staff will slow down your vehicle. So if you're placed in the back it's a challenge to take the lead as difficult to pass others. Overall a fun experience

I came to K1 Speed earlier tonight hoping to have a good time. My wife accompanied me, and…read moreinitially I thought everything would go smoothly. Unfortunately, that was not the case. When I arrived, I was informed that the wait time for my first race would be over an hour. I accepted that and decided to order food while I waited. After waiting approximately 30 minutes, the food arrived undercooked and incomplete. I returned it and requested a refund rather than canceling my visit entirely because I still wanted to participate in the races. When I finally got into my first race, there was an issue with my kart. The problem was eventually corrected, and I completed the race. However, during the second race, the kart failed completely. I started the race in a leading position, but my kart stopped functioning and effectively ended my race. At that point, I requested a refund because I do not believe it is acceptable to pay premium prices for an experience where the equipment is not operating properly. The karts should be maintained and race ready, especially in a competitive environment where lap times and performance records are an important part of the experience. I come to K1 Speed because I enjoy racing and competing, not because I want to spend my time dealing with equipment failures. I have spent a significant amount of money with K1 Speed over time and generally enjoy racing on your tracks. That is why I was particularly disappointed with this location. In my experience, other K1 Speed locations maintain a much higher standard. Additionally, the condition of the bathrooms was below expectations. For example, water was coming out of the flush button when it was pressed, which is clearly a maintenance issue that needs attention. I genuinely enjoy K1 Speed and would like to continue visiting. My recommendation is that this location receive additional attention regarding maintenance, cleanliness, and equipment reliability. There appear to be operational issues that need to be addressed. I hope management takes these concerns seriously and works to bring this location up to the standard I have experienced at other K1 Speed venues.

Experience: 4/5｜Service: 4/5｜Facility: 4.5/5…read more We booked our session through Groupon, which helped save a bit compared to regular pricing. Even with a reservation, it was quite busy the day we went, so there was still a check-in process to go through at the front. That said, everything was organized and moved along reasonably well considering the crowd. I've been to another K1 Speed location before, and this one definitely feels newer and cleaner. The facility is well-maintained, and the helmets were in good condition with no unpleasant odors -- something I really appreciated. The overall environment felt safe and modern. We brought a child with us and asked if it was possible to group them with other kids. The staff was very accommodating and explained the different kart ranges available for younger drivers. They made sure everything was age-appropriate while still keeping the experience fun. As for the track itself, it was exciting and well-designed. The karts were responsive, and the layout had enough turns and straightaways to keep things engaging without feeling overwhelming. Overall, a fun and energetic experience -- especially great for families -- and I'd definitely consider coming back again.

Waiting 30 minutes for a pretzel and onion rings sucks, it especially sucks when the onion rings taste horrible and look just as bad. Its even worse that you ordered prior to a party arriving and yet they got at least two orders of wings and pizzas delivered before your food even hit the table. Install a notification system, minus 1 star. Waiting an hour and a half to ride is fine. Not being able to leave is the problem. Its 2026 and you can't have a push notification system for guest....maybe its better with a reservation but living over an hour away and with California's traffic its not something that can be guaranteed for some. It wouldn't be fair to not review the actual thing people come here for. The racing is fun and exciting. Course is done well. Plus 1 star.

However,karts there are terribly maintained,there are only 2 fast karts in a whole row of over 15,you do not get to choose your karts,you get assigned to them.A huge issue with the karts are the seats,the karts are so recked that the seats are sideways,they are not facing the steering wheel,they are like 5-20 degrees off the right or left side.(Only like 2 karts don't have this issue)top speed of the karts are quite high,however the pick up is extremely extremely slow on most of the karts(one of the good kart is no.43) The track is quite wide,wide enough to make mistakes.However i heard they change their track often so if i remember the name right the name of the track i raced was north smth.It was a little too short but good corners.

We got 3 races plus the bronze license which was about $200 per person in total. With this we got gloves and a head wrap thing to keep and you can use their helmets and jumpsuits. We were under the impression you had to wear long sleeves and pants period. BUT turns out you can either wear the long clothes (and just race like that) OR you can have short stuff on and use a jumpsuit. Thank you to the really nice patron that told us that! It is soooo hot out there and a jumpsuit over long clothes was suffocating and unbearable. We went on a Wednesday around 1130am for races starting at noon and had no real issues . All the employees were super nice and didn't give any attitude. The races were about 15-20 minutes apart. We called days ahead and were told weekends were their busiest days and you would likely be waiting over an hour in between races . No thanks. It looked very new and legit , like they hold actual racing tournaments there (I'm sure they do but we didn't ask). Very clean and the tater tots were delicioussss. We got all the information we needed at the very beginning. If anyone is like me , big doses of information go in one ear and out the other . With that being said I wish it was more beginner friendly. We were given all the information and were sent on our way. We didn't really know where to go, just kinda figured it out . Most of the help we got was from the very friendly patron mention above. Just little questions we had like "can we take our water bottle with us" or "can we leave our stuff out here?" ALSO , I am 5'9. My man is 6'3. Those carts are not meant for tall folks lol . The first race I kept getting cramps in my calf. By race 2 I was slightly more comfortable. Race 3 I didn't really notice as much anymore but just know, it is definitely and adjustment. All and all, really amazing experience. I'll give it a 4 because although the employees were nice and answered questions when we saw them, I wish we had like someone to guide us through it all being that it was our first time. At least for the first race. We will likely come back being that the license lasts a year but thank you guys for the awesome experience!
