Klein is not like other Istanbul clubs. "It's just like Berghain," someone said in the queue outside, referring to the infamous Berlin nightclub. And he was right, to a point: like Berghain, Klein is big, the music is powerful, and the people are not just there to be seen - they're there to dance. But the endless game of comparing Istanbul nightlife to other cities does not do Klein justice. This is one place that couldn't exist anywhere but Istanbul.
