Favorite italian restaurant, great simple food, friendly staff and the coolest atmosphere (vinil music only). Smart to make a reservation before you go.
A very good reason to travel West: the C/O, next to the formerly infamous Berliner Zoo tube station, is an awesome museum dedicated to photography and visual media. Previous exhibitions include Larry Clark, Martin Parr, Anton Corbijn, Annie Leibovitz and Stephen Shore.
I often go exploring into random and dilapidated areas of Berlin. I like the thrill of finding new nooks and crannies with strange visual sites. A few months ago, an old housing colony was abandoned, and many objects (such as couches and front doors) were left at the edge of the city to rot or to be scavenged. This is a view from a non-descript area of the S-bahn train tracks (between Sonnennallee station and Treptower Park station) into the most Southern part of Neukölln district.
