Kw is a great art institute situated at the backyard of a very eastern part of town, place for many other small galleries. Auguststrasse is worth the walk and Kw is worth the stop.
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.
