Berghain was historically a gay club and still plays an important role in providing a safe space for the queer, techno-loving community to do as they please.
Don't be rowdy or chat loudly in the line, and know which DJ is playing that night since you might be asked. Also, make sure you have €20 cash for the cover.
You should also snack and pre-drink before heading to Berghain because there aren’t many food options inside and club drinks are considered expensive in Berlin.
However, if you plan on drinking at Berghain, it has a variety of beer options, mixed drinks, non-alcoholic BioZisch sodas, and tea-based energy drinks called Club Mate.
