I posted something similar in Hamburg forum too, but I need somewhere I can hang out in Ku'damm area late at night. The catch: I don't drink, dance, speak very good German, am alone and female. I heard there are many places open till late in the area, but the question is, can I stay there with just a glass or two of soft drinks (or bottomless cup of coffee if there is a thing like that in Germany)? German equivalent of Denny's will do.... Your 2 pennies will be much appreciated.
