Yes, but not in the night. I was showing them round 1'o clock in the night - there was so few people. Usually normal citizens don't go to these places if they don't have to.
And yes, Vinohrady and Zizkov are the best places in Prague to hang out. Soooo maaannny puuuubs there!
When did you visit Praha? Do you know that it is now very popular among young Britons. They buy cheap airtickets (Smartwings, eg.), drink here the whole weekend and then go back to the UK. I even hanged out with couple of groups of British tourists.
They could be recognized from far away - all these umbro clothing, greased (or bold) hair, very often so fucked up they shout and do mess, hehe.
