Well you can still wander around Tempelhof 
Don’t forget Tiergarten. One of my best pals lives there so I am really shit at remembering where I’ve eaten and drunk as she just takes us to all the cool places.
Have you ever been to Berlin before? I’m trying to remember the touristy stuff- obvs the East Side Gallery / Holocaust Memorial. The DDR Museum is shit compared to the Stasi Museum. There’s also Checkpoint Charlie, the Topography of Terror and the Jewish Museum.
There’s a computer games museum which looks radical but I’ve never been. Bauhaus gallery or whatever it is, is crap, apparently. The Gedenkstaette Berlin-Hohenschoenhausen looks good if you like that sort of thing.
