I haven't visited the clubs in many years. My entertainment dollars are better and more enjoyably spent elseTER, I mean elsewhere
, if you catch my drift.
FlashDancers (my personal favorite back then) used to be the flagship club of, I think, 3 or 4 other sister clubs: same owners, dancers would move around, as needed, similar but not the same policies. One place, around 34th and 3rd was totally nude and nude lap dances (not table dances, LAP dances); the nudie place is long gone. Private Eyes (E 45th) is a sister club. NY Dolls (financial district) is a sister club.
There are many other "gentlemen's clubs" around town not related to FD: Scores (West 28th?) gets a lot of press because of illegal activities there - I'd avoid it; Legs Diamond still exist? Lace, Hustler Club. And many more.
Watch out for the "Champagne Room" or other private rooms. It will set you back a bundle for, usually, not much more than you get on the main floor. At the legal places (FD, Lace, etc.), the bouncers keep a watchful eye on things. Their liquor license and "open hours" are their money makers and they do not want to be shuttered for any reason. They have zero tolerance for illegal activity (bj's in the back rooms) and you'll get thrown out if caught. No, they won't wait 5 minutes for her to finish; you're finished!
SBB left out specific mention of the Brazilians. There used to be bunch at FD. Wow. I remember the four sisters: Jane, Julia, Joanna, and J--- I forget the fourth J-sister!
But SBB is right: they will drain your wallet and leave you with blue balls.
Another recent thread here asked about Candy's DVDs and Bliss: two other club-like places.
You should note: FD, Private Eyes, Lace, etc are all legal establishments. Bliss, Candy's, are more underground and questionable.
Then there is Club TER

which is whole other ball game
