Striptease clubs in Copenhagen are alright, at least for what they are supposed to be: nightclubs with naked babes. But if you’re looking for some more explicit action you need to be aware they do not offer the best opportunities in the Danish capital.
Copenhagen has some great strip clubs with beautiful dancers and strippers but don't count on any "extra action" behind the scenes
The bottom line is that they are safe and fun, but also famously overpriced. Some of the best strip clubs in Copenhagen are Bada Bing (https://badabingcph.dk/) at Gothersgade 19 and Lady Love (http://ladylove.dk/) at Helgolandsgade 2.
Copenhagen Sauna Club (https://copenhagensaunaclub.dk/) at Ålekistevej 230 is what I’d personally recommend.
It’s an adult sauna club, rather similar to the concept of a German FKK club: with spa facilities and many attractive upscale “hostesses” representing all kinds of nationalities. So it’s definitely worth checking out if you are open to explore more intimate adventures than you would be served in a regular strip club.
