Monterey Bar, Danzigerstrasse, Prenzlauer.
The first Australian I met in Berlin was a Melbourne guy who owns this bar. I went in because of the craft beer signs outside. Basically has beer, whisky and rock and roll late).
Like a lot of bars I’ve been to in Berlin this one doesn’t open until 6pm or 7pm. In this case Adie and his partner also run Alternative Berlin tours so they have a day job. (alternativeberlin.com/ )
