My favourite bar of the many around kreuzkölln is Bellman. After its sudden closure and reopening it underwent some changes and is boycotted by some of its former patronage, but for the less principled like myself it’s still a good place to go and they do pull the best Jever in Berlin.
Haus der Materialisierung is an association of various local initiatives and institutions that research, practice, and work on the topics of sustainable management and climate-friendly use of resources.
...and it works!
This museum of photography is really great, and the highlight for me after the inspiring exhibitions is the good coffee and great cakes at their coffee place.
I find myself there almost every second week for a drink and a slice of cake. The food is perfect, the ambiance is nice and it's really alive as a lot of people are coming directly from the running exhibition. At the entrance you can find an interesting bookstore and the best photoautomat of the city right outside.
Last but not least, it's only some meters from the Helmut Newton Fondation ( which doesn't have a nice coffee place itself yet ).
