What a location! We tried it out right after the Jazz concert in Rheinaue, attracted by the Ladies' Night special offer (you'll get an unlimited number of Proseccos between 10 and 1 as long as you are female and pay the entrance fee).
We arrived there at 11 p.m. - and were the only customers at this time. However, there might have been some others, but it would have been impossible to see them because of all the fog in there. So we were pleased to have a disco of our own!!! Music was good, and while several other people made their way through the fog, we enjoyed ourselves and dancing till late...
Hint: Make a reservation for a place on the cosy-looking couch!
