Not much to add to other reviews - great place to chill out and play some old school games for spare change. this is probably going to become a regular stop for me....and a top recommendation to friends who visit.
This place is maintained by volunteers who donate their profits to charity (or so I was told by a couple of operators). Freaking awesome.
Be sure to try Pinball Circus, super fun, one of a kind game (only two built) that never made it to production but one is here!
The 'Relaxalator' over by the vending, try it out!
No entrance fee, just put quarters in the machines!
