LeTrapeze on E.23 (?) and 5th is the only one I've been to. It was my first and last time in a swing club. I didn't like it. Found it sleazy ( mostly pimps and their women). I could only watch, I was worried it may be a health risk. In any case, check it out. I think it is the most well known in NYC at this time. I have heard others in place like Arizona are much more posh and health regulated. Good luck.
