Well, I am showing a mate around on Friday night and the sunny weather makes it a whole lot either... I am biased but you cant go too far wrong with Kries 5.

Few evening beers by the Letten Badi, decent bars/restaurants around the Langstrasse when the sun goes down (Long Street bar, Acapulco, Mata Hari, West Side, Josef, Cafe Rossi etc),

If you want to go on, then its a 15 min walk down towards Hard Strasse and all the places there (Hive, Supermarket, Besame Mucho, Toni, Moods, Labor).
