Champs karting is a lot of fun. It is an indoor electric go kart race facility that caters mainly to groups that have made reservations in advance. Although, if there is no group racing, the place is open to the public. Just call ahead to see if the venue is "closed off" for a private party before you decide to show-up for a race. 425.455.9999
After your race(s) have a beer and hang out for a while watching one of the big screens, playing pool or watching another race.
