In a strange post-apocalyptic world there is Cafe Flesh. Part cabaret, part insane asylum, Cafe Flesh (http://cosmic-cinema.blogspot.com/2008/10/cafe-flesh.html) makes Caligula look like Bambi.
The review is here (http://cosmic-cinema.blogspot.com/2008/10/cafe-flesh.html).
A classic.
The sequels are just as weird and silly.
