a couple of amazing places…
if you like schnitzel (and who doesn’t?) then Austria on BergmannstraBe is the place to go as the schnitzel is gargantuan and incredibly tasty… its one all manner of awards for the past 10 yrs or so..you might have to book in advance, and if you look a bit german like i do then they won’t believe you’re english and continue to speak german to you (and english to the others at the table)

Also oranienstraBe has some decent places to go (towards oranienplatz)and theres a row of bars in railway arches heading towards museum island from alexandersplatz, they have a small green out the front of them and are by the railway bridge and tram lines…. really close to the pergammon museum..
Good luck and enjoy – its the best place ever…
