I've only ever been to the Mini Grand Prix and that was well more than 5 years ago. With that being said, this place is pretty decent for it's giving. I go with friends and we usually purchase the GroupOn. This includes two races, some water, and rental gear. The karts itself seem pretty slow but when you start driving it's not so bad. Only rating four stars because they always slow down karts. Could be for safety or fair play, but I'm not sure. I'd say to give this place a try and see how you like it!
