What's not to like about Berlin Bar? The weissbier is a-flowin' and the crowd is a-glowin' (during…read morefootball matches, at least)!
You basically go here for German beer. And if you're German or a big fan of the culture, you might also go for football matches or the general "deutsche" atmosphere. Nothing wrong with that, though I would visit the bar mostly for the beer.
And there is so much of it in Berlin Bar! All sorts of the gorgeous liquid can be had, but you have to have some decent knowledge of German/beer to be able to understand the menu. Or just ask for help from the super friendly staff.
I once visited Berlin Bar after Germany had won a world cup match. One could say the atmosphere was euphoric. Which I didn't mind, even though football is not a big passion of mine.
Football or no football, Berlin Bar is always a good place to quench that thirst for decent beer!
