Berghain

Carlos says

This is the Techno and Electronic Cathedral in Berlin. Keep in mind that lots of people come here, you can be in the line to get in for hours before getting to the door, and that you might not get in at all. The bouncers at the door decides who gets in and who doesn't, it's all a matter of luck and attitude. Be openminded, don't wear your best clothes (always choose black) and be as discrete as possible in the line. Also, don't dare to take your phone out of your pocket!
