- the music will be very very loud to discourage actual conversation. Though you can try to talk to the girls there, usually it wll be limited to something like "do you want a dance" and "yes" anything beyond that will be hard to make out.
- never heard of a strip club not serving alcohol. Often the girls will try to get you to "buy them a drink", which means you get to sit and talk to them for five minutes in exchange for paying for a $10 beverage (even steeper than they usually charge). Of course, over the music you can't really hear anything. If you buy a drink for yourself it will probably run $3-$8.
- expect to pay a cover if you go during peak hours. A lot of clubs will let in guests for free during off-peak hours, and some are free all the time, but most of the time you'll be paying $5-$20 at the door.
- once inside, there will usually be a central stage where the girls do poll dances and strip teases. There will be chairs lined up close to the stage where you can get the best view. If you sit in these chairs, they will expect you to deposit dollar bills in the strippers' g-string or toss them on stage. You don't have to do this for every girl, but they'll want you to. If you hold the dollar out, they'll come over and rub their titties or ass in your face. Unless NY is one of those weird states where there is a rule against touching. They will usually strip down to fully nude, some states don't allow bottom nudity, some states make them wear pasties on their nipples. If you are sitting in one of the chairs by the stage and not handing out dollars, the girls will get pissy.
- there will also be girls walking around, sometimes offering to sell drinks, usually trying to get you to agree to a private dance. They will all usually act very friendly and as if they are interested in you. They are not. They only want your $20. If you refuse private dances from enough of them, their attitude will often shift from friendly and flirtatious to bitchy and mean pretty quick.
- If you do agree to a private dance, you can get a lap dance or table dance most of the time. Table dance they will do a private strip tease for you at the table on the floor. Lap dance or private dance they will generally take you to a private booth and do a private strip tease for you there, generally much closer and with more touching involved depending on the place and the local laws. Some will get totally nude, others will leave certain garments off. Some will allow you to touch them, others will tie your hands. If they let you touch, they might allow so much as you to suck on their nipples or maybe even finger their pussy a bit, but probably not. A few may try to dry hump you through your clothes. If they do any of this stuff, they will probably try to work up to it. One "dance" is usually $20 and lasts maybe all of four minutes, or one song. They might not even get completely nude during this and then they'll try to talk you into doing one more dance after another, often suggesting that they might go just a little bit further if you pay for one more dance. Be careful with this, in a few minutes you could go through enough twenties to pay for a real hooker.
- some strippers will perform sexual favors. Including blow-jobs or even straight sex. Many work as prostitutes in addition to stripping and may offer to come back to your place with you if you pay them enough. This is almost invariably against the house rules though, and many girls will get offended if you ask. You could get anything from a stern rebuke to getting thrown out of the club on your ass, depending on how you ask and how forward you are.
So, in summation, expect to pay maybe $10 at the door, another $5 if you want to sit up front for the main strip tease, maybe $40 if you agree to a private dance, $20 for drinks, and another $5 if you're dumb enough to use the ATM machine on-site, which always has outrageous service fees.
Good rule of thumb, just be careful what you agree to. All these girls are trained to flirt to get your money, they know what works. Remember you don't have to pay for anything you don't want and no matter how generous you are and how well you tip, except in very rare cases, none of them are actually genuinely interested in you. Be careful about looking for/asking for sexual favors... and if you go that route, be prepared to spend another $50-$500 depending on the girl, the place, and what exactly you ask for. (though... don't get suckered into paying that much... $300 can get you an hour alone with an escort that looks like she just walked off the fashion runway. Or $150 will get you a nice massage, body wash, and fuck from some cute Korean girl who doesn't speak English. If sex is what you want, that's a much better use of your money)
and though this should be self-evident, for god's sake, make sure you've got a condom. Any real sex professional will have them on her, if you encounter one who doesn't, that's all the MORE reason you should use one.
