Hustler Club is actually free if you go to their website and show them the free admission pass (don't even have to bother printing it, you can show them from your phone). Otherwise I think its $20. But you are right that it's a pretty good place. Has a roof top. 10 minute private dances are $120 which is one of the cheapest I've seen in the city. And $585 (with credit card) gets you 30 mins downstairs in a private room). And the selection seems to always vary every couple of months.

Other places I've been to that I liked were Flashdancers and Rick's Cabaret. The latter has a rooftop as well. Sapphire is interesting if only because they seem to have pornstars that tour there every weekend. I went there once though and it was just way too much going on for me (may have been that I chose to go on a holiday and there were literally so many ladies there that I couldn't tell if they were working there or not). VIP is another good club. Also liked Rick's Cabaret's sister club Vivid. I would avoid Dolls (sister club to Flashdancers, there's another one I think called Privates that's supposed to be one step away from Flashdancers in terms of talent) as the seating arrangement quite frankly blows, girls weren't that great, and everything is really tight (last went a 3 years ago maybe?).

I could go on mentioning other places but unless you're going to hit multiple spots in one night then you can't go wrong with any of the ones mentioned so far. I haven't been to Penthouse. Should check that out sometime.
