> Everybody says you need to wear black.
That is false.
Look, if you just made it for everybody, it would no longer be a club with an underground image. Berghain is a tourist magnet because it simply is an unbelievable location straight out of a Mad Max movie, paired with a Funktion-One sound system that fits your head like a headphone, featuring the best techno DJs in the world, and you can spend your whole weekend there without ever leaving the club. They surely do not struggle financially, on the contrary, the owners are probably swimming in money and only still do it because it's fun.
Besides, let me say there's lots of other clubs in Berlin you can go to. The article is correct that there used to be much, much more, but the main issue for clubs is not attendance, but like pretty much in every big city: rising rent and neighbors who complain about noise and garbage.
