Went to one in '98 at Kunstpark Ost
which was actually alright ...it was the usual sex shop type thing, decent enough strippers on stage, a special room for private dances and 'supposedly' innovative new toys and thrills.
One of the latest things was a 'rotating loveseat' which you hung from a hook in your living room and used to swing into your missus with ...there was a hole in the middle to stick your tackle through like. The training video that they were showing was priceless !
At the time it was something like 15 Deutschmarks to get in ...sounds from the latest visits in this thread that things have gone downhill though ...
