I've only heard great things about KitKat even from people who live in Berlin. It's a bit of a Mekka according to the people in the scene here.

The scene is prone to issues and what we do in my town is not allowing new people unless they have a fet account and/or accompanied by a regular. Not sure if that's the case over there.

I really hope I can visit it one day but I'm really afraid of travelling all the way there and being refused..
