I have been several times, with my wife and alone. Usually lots of guys in there and some times a few couples. Very fun. Easy why to give and receive some head etc...
Easy. Go up to the counter like you have a pair. Pick a theatre. Buy admission, but pick gay or straight. You walk pretty far back once you go in the theatre, but that's so you know someone new walked in. The theaters are just regular size TVs in large rooms with chairs. Hallway well lit, all dark theatre. A lot of guys there. Then individual arcade rooms in same area. Little unsettling at first, but relax. There will be an assumption that you are there for company and assistance by other customers, so be prepared to allow or POLITELY say you don't need any help. I got a little creeped out and left, but felt fine the next time. Bring your own Kleenex.
