K1 Speed at 17221 Von Karman Avenue, Irvine, California.

The place is great. The staff at the front desk are always friendly and helpful and there is a lot you can do while waiting to race. You can get something to drink, watch tv and race on a video game simulator. The track is fun too with fast sweeping turns and sharp hairpins. The only issue I really have is the karts can sometimes lose power over the course of a race even without pressing both pedals at the same time. Overall, a great place to have parties or to race with your friends. Easy parking too.
