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.
ABC is Berlin´s Eggs Benedict Mecca. This laid-back, fun little shop will provide you with one of the city´s best Aussie brunches - provided you reserve or are willing to wait for some time. But the eggs, the coffee and the Bloody Mary really make it worth.
A very close friend of mine owns this bar. It looks tiny from the outside, but it has two rooms you have to pass until you get to last one which is a discofloor. I play music there from time to time and I am always surrounded by nice people und friends.
