Just until recently this place used to be one big old Aphoteke (Pharmacy). They have kept the Apotheke's  dark wood Art Deco charm to use in benefit of great coffee and fantastic brunch (try the french toast and you'll see I'm not lying). 

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 ).

KINDL- Center for Contemporary Art. It’s an old brewery that has been transformed into an Art Center, … both galleries often have unusual, beautiful and thought provoking shows.

It's a small bookshop to be stuck forever. Here you can find the most beautiful collection of art/photography/architecture/fashion/food books and magazines, not to count it's just a walk distance to diverse galleries around the neighborhood.

I never knew this neighbourhood existed and went to visit a friend and was instantly transported out of Berlin into some sort of 50's utopia. "The Hansaviertel is a prime example of modern architecture and urban planning in the fifties in Berlin. 36 individual buildings or ensembles still form the model of modern architecture and urban planning of the 1950s. The southern part of the war-damaged Hansaviertel, which lies between the S-Bahn line and Tiergarten, was chosen as the central demonstration area of ​​the International Building Exhibition in order to present the "city of tomorrow" - in deliberate contrast to the East Berlin Stalinallee and the restored tenement barracks." - berlin.de Also visit The Akademie der Künste, if not for the art then the architecture alone.
