You didn't give much notice. I hope you found some good stuff. For future reference, here are some suggestions I recently gave a friend:http://www.hopsandbarley-berlin.de/
- Strange little place, a little smokey, but the beer is solid. Probably the best I've had in Berlin. My friend has had good experiences there as well.http://foerstersfeinebiere.de/
- Great little beer bar, serving only quality German beers. Some meaty food options as well. Very cool people running the place. https://www.facebook.com/hopfenreichberlin/
- Pretty cool hipster craft beer bar. Very well chosen selection. If they have Spent Brewers Collective beers, go with those.http://heidenpeters.de/
- The beers are actually not very good, but the location is cool. They're in a fairly trendy market hall with lots of good, cheap food options. Beware - the food stalls close pretty early.
