Highly recommended - get the Groupon, get good times!
After the introductory video, you're able to put on the racing sock, helmet, and join up to 14 other go-kart racers on the curvy track.
You drive in "races" which are essentially sets of about 10 laps each. You may be driving with other groups of folks and theoretically, you're not supposed to bump cars, but the staff is pretty liberal and good at making sure you can do whatever you can in the car while having a good time safely (i.e. prepare to bump or be bumped, and drift as much as you like!)
The cars themselves are pretty fast, especially for this outdoor track, where a lot of turns prevent much straight line acceleration. The service is pretty casual but good.
Regular price is $25 for one race and $20 for a second race. I recommend getting the Groupon deal ahead of time (same day is ok), which is $25 for one person to enjoy two races and a bottle of water. $45 can get you the same deal for two people.
