Anyone know any good Adult Cinemas?

Wife and I have got a fantasy we want to fulfill of heading to an adult cinema, watching some porn and getting each other off with some extra exhibitionism for her. Be great if it was somewhere known for couples going to, not just other men but difficult to find anywhere these days and wondering if we might need to have a dirty weekend further afield somewhere like Amsterdam.
