Quartier Kreuzberg ("remains a place of punks, graffiti and politics (handbills emblazoned with signs shout "Stop gentrification!") and it's also home to many communities of gays and Turks, trendies and crusties, thinkers and drinkers")
Café Anna Blume in Berlin Prenzlauer Berg. Perfect for a lazy sunday eating the good cakes. There's a flower shop inside and you can even take a book in the trunk as long as you replace it with one of your own.
