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 ).

My favourite book store with a minimal interior and maximum range of books on architecture, design, art, philosophy and politics. 

If you want something a little different from your beer, try Lager Lager. "We are an independent bottle shop and taproom in Neukölln with a passion for all things beer. Choose from our 8 rotating taps and 250+ bottles, with new stock arriving each week. Drink in or takeaway a Growler bottle of your favourite beer using our counter-pressure bottle filler, which guarantees freshness."

It's an old entertainment park. It's closed now, but you can sneek in and see how nature has eaten the place up. Really nice to take pictures.

While strolling around Mitte, check out the flagship store of Berlin´s cult women fashion brand. (And try a delicious cinnamon bun at Zeit für Brot next door.)
