I think I saw at least three erottic bars, I didn't go in so I couldn't tell you any prices. There was a pole dancer in Rila night club on Sunday night, I think, I lost track of the days drinking 2 Leva pints.
Give the guy a break he asked an honest question. There is nothing illegal about an erotic bar, here or in Bulgaria. There are enough people talking about getting pissed and nobody gives them a hard time (not that i think they should).
