Re: central/south jersey?
there really aren't any good bikini bars in central Jersey. If you were up for nude work I would recommend Delilah's in South Amboy. If you're willing to go all the way south to Atlantic City there are a few decent options, but that's a lot of miles. There's also the option of going north across the NY border within a 1/2 hour's drive time - Lace in West Nyack is a very decent topless club, and topless always outsells bikinis.

There's a bikini bar in Gloucester, NJ called Cheerleaders. I hear good things about it.
