I only know Cocoon. A very nice club - on the small side compared to the Frankfurt ones, but very laid back and comfortable. I have had good service there on my four visits. Including one memorable one where two girls ganged up on me in the brightly lit main room and had a wild time till I came over their faces. I was so embarrassed but they had a great time!. You pay when you leave, Few of the girls speak English. You can get there by public transport (use
www.bahn.de for info) - if you use a taxi it is only seven or eight minutes from Wuppertal-Oberbarmen
