Pole Position Raceway is an indoor go kart track with high speed cars. Went there on a week day night and there was a nice crowd there. This location is new compared to the ones closer to the strip.
When you race you do 15 laps and they track your progress, you get a print out on how you did and your best lap and times. It's a lot of fun. Besides go karting they have arcade games like basketball, air hockey, pool, and other video games. If you are going with kids they do different races for adults and kids so you don't have to worry about them going around hairpin turns with guys that think there in NASCAR.
It is on the expensive side just to let you know. It's $25 per person. Sometimes you can find a 2nd ride free coupon in the paper or here on yelp, but it's non transferable so don't think you are getting away with a cheaper date! They do offer monthly and yearly passes which is nice if this is really your calling.
