A restaurant near S-Bahn Friedrichstr, but I never tried their food, only drinks. I went there by accident the second week I was in Berlin, and fell in love instantly. Their foamy Schultheiss is the best I ever experienced (most probably because I was new back then, in addition to enormous local bar feeling). No more than 4 euro for this 0.4L Schultheiss. Drink at the bar with some friends: the best.
