Howdy. Might I suggest you look at my summer report from this year, where I mention a goodly number of delectable eateries and bars, and get back to me with more specific requests in case what you desire hasn’t been mentioned.
I second @honkman’s recommendation to have at least one döner & one currywurst, though I wouldn’t waste a planned meal on the latter - it’s a snack best enjoyed hammered, and Curry 36 is a good & famous place to do so. Curry Baude near the subway Gesundbrunnen is famous for their varied levels of heat in their curry sauce, but I’ve never been.
Great döner can be had almost anywhere, but notable ones are at Rosenthaler Platz Schlemmerbuffet in Mitte, Imren (different style than the usual döner on freshly baked flatbread) on Kottbusser Damm in Neukölln, and Pamfylia in Wedding (happy veal, fantastic).
