Berlin is not really a real impressive restaurant town, although there are some little gems around if you are familiar enough with the city, but I am surprised that no one has mentioned KaDeWe , the 6th floor. I have been in Berlin many times and really the fun thing, food-wise, to do IMO is go there. Plan your day around lunch and go there. Keep dinner light. Berlin seems to have a pipline to some good fresh fish and seafood (not all of it by the way. The Lobster I had last month there was frozen, ugh.) and all that seafood is sold at KaDeWe. It is actually a great business model. (Paul Bocuse actually had an outlet up there until just recently. And, shock of shocks, that was where I had the frozen lobster. NZ not Canadian). The Paris bakery Lenotre has a little cafe on the 6th floor also. They had the single best simple chocolate torte that I have ever had, it is called L'Etoile if anyone goes up there. I have been to Berlin twice in the last month and recently had an oyster orgy at KaDeWe. One little cafe on the 6th had oysters from 6 different European areas. Way interesting but as usual the ones from Brittany were the best . For restaurants, per se, the only places we return to are this little Chinese place called Good Friends and right next door is a little Japanese/Korean sushi and yaki bar (great crispy chicken-skin yaki. One is enough but very intersting to try) You can find them near to the corner of Bliebtreustrasse and Kant Strasse. About one block off Kuferstendamm right in the center of W. Berlin.
