Zola is a Neapolitan style pizza joint hidden inside a Kreuzberg backyard. This is a killer pizza place, one of the best in Berlin without a doubt. 

Wim Wenders shot Wings of Desire here. It's a quiet place to work and definitely a gorgeous place to visit. Combine it with a visit to the Philharmonic, just across the street. Affiliation is 30 euros per year and you have lots of desks all over the library to choose from.

It's an indoor market, which makes it a great option in winter if you are looking for anything from kitsch to classy. I like it because you find lots of old objects that transport you to the past.

Art bookstore for the more off-the-grid publications.

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.
