I've been to a couple of Vegas strip clubs. The upscale ones like Scores and Sapphire tend to be very nice and have the most beautiful women, but they are also very expensive; you'll usually end up paying $30 - $40 at the door (if you are with a large group of guys, you may be able to convince the doorman to let you all in without a cover charge as long as you order drinks immediately upon sitting down), a simple domestic **** will cost you about $6 each, and lap dances are $20 each (private dances in the VIP room usually start at $100 for 3 songs). So if you want to go to one of the nice strip clubs you should expect to spend a lot of money. You should also know that if a strip club in Las Vegas serves *******, the girls are not allowed to go fully-nude, only topless.
Although I've never been there, a friend of mine has told me good things about Little Darlings. Because it doesn't serve ******* the girls are allowed to dance fully nude, plus the lap dances are supposed to be pretty good too.
