Just an amazing cup of cappuccino. Try the Franzbrötchen with it for a basic breakfast. It's a place for someone who appreciates good coffee done with extreme care.
Kw is a great art institute situated at the backyard of a very eastern part of town, place for many other small galleries. Auguststrasse is worth the walk and Kw is worth the stop.
A place where I spend some time almost everyday is the Marheineke Markthalle on Bergmannstraße in Kreuzberg. It's just around the corner from where I live and a great place to buy fresh food and products from local farmers or all kinds of delicatessen from different countries. Many market stalls also sell freshly prepared food and it's always busy at lunchtime. For saturday mornings try the original french croissants.
What’s not to like about The Sammlung Boros Collection? It’s a brilliant private collection of contemporary art held captive in a monstrous, symmetrical ex-Nazi bunker with two metre thick concrete walls, dominating an area of a thousand metres squared. It also doubled as a hardcore techno and fetish club in the ‘90s, of which traces linger in every corner.
