Sure, you could go back to your hotel after dinner, watch some T.V., and make an early night of it. But if you did that, you´d be missing out on one of the most exciting nightlife scenes in the world. Clubs that attract Europe´s most energetic partiers and famous D.J.s, as well as bars and lounges where the decor alone is worth seeing. Looking for something more relaxed? The classic german beer garden is a great place to spend a summer night and enjoy a pint (or two) with the locals.
