I've been in Casa Rosso it was 35€ or 50€, can't remember. My local friends said it is the only place worth going and so I did. It was bit weird experience sit in a huge audience with masturbating asian guys.
The sex was hardcore and if I remember right there was also a plot in the show. I was stoned as hell so sorry but I remember it was fun experience as only live sex show I ever been. There was a lots of humour example the masturbating monkey-suited guy.
