Tower Bar, Hamburg
Go when the sun is set and you'll get a FANTASTIC view of Hamburg's port at night!
Worth it. You go there for the view, not the people. Go there with someone, it is not a place to flirt.
Dress Code: People were chic, but I wasn't. Urban dress code, I guess.
The best view over the habour you have from the Tower Bar. At the beginning of the Reeperbahn (Millerntorplatz) just walk left and at the end left again. Go in the hotel Hafen Hamburg, drive to the top, and just enjoy!
