Tuesday's lunch hour tip is the amazing Berlin Philarmonic. A short-duration concert (around an hour) happens every Tuesday at 13h, for free. People make the Philarmonie's foyer full, sitting on the stairs, on the ground and everywhere around. Little advice: bring with you a little cushion for more comfort and try to arrive early to find the good spots.

The Hamburger Bahnhof – 'Museum für Gegenwart' which was originally a train station is a terrific museum featuring a selection of contemporary art.

Interesting and surreal window shopping around Neukolln.

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). 

Peres Projects mostly showcases young, emerging artists and is at the forefront of fusing art with fashion, celebrity and the love of a good party, which seems to work very well in Berlin. Having recently moved into an ex-Soviet building on Karl Marx Allee, the giant new space contrasts brilliantly with the commanding facade.
