In Russia these are very abundant now. But not a place I suggest you go. They are full of young ladies waiting to get your money, yes, they will sleep with you, but the price may be more than your willing to pay, and other less desirable people also go there. Also with the recent spy scandal and arrest and conviction of an American student in Voronehzh, for a small amount of drugs under suspicious circumstances, (it is suggested it was a setup) I would suggest staying away from night clubs as the arrest took place there while he was with a young lady patron.
