hey there, i cant give you an answer on your latest question but i can tell you that even for girls the reeperbahn in hamburg is kind of funny. i just went to hamburg in april with school and had some great evenings in "große freiheit 36" (it means "huge freedom") on the reeperbahn. in the basement that is named "kaiserkeller" you may find people that prefer different music and entertainment than what you find in "doll house" across the street .. or other stripbars. one evening a really interesting band had a concert in there. on other days i think it is used as a club. unfortunately i only spent a few days there and i went to a goth-evening in kaiserkeller, which is not the music or scene that i prefer most of the time, but is was pretty interesting and much better than the dumb clubs most of my classmates went to. although, i wouldnt go there without any guys ^^
heres a photo of the club i took myself - maybe you would like to find it ^^
