In reality the bar is cool, I just find it a bit of a shame that the music is really loud even though it's early, it prevents you from fully enjoying the place but the atmosphere is there!
I also find that the choice of beer is not necessarily very varied, but the other drinks on sale compensate for this lack of choice.
I recently visited the Berliner Bar and found the experience to be okay, but not exceptional. The service was good and the atmosphere in the bar was pretty average. The prices were average of what one would expect for this type of establishment. Overall, it was a visit without major problems but without particular brilliance.
