Go to Dom Vikingrow in the main square
I don't like this place. People here seem old and it's too relaxed.
Blue note is ok, but it's usually hip hop.SQ is mostly House and Chill out.
Lizzard King is a nice atmosphere. Plays mostly rock, but not a club.
A popular foreign place is Dragon bar. I really like the atmosphere. It's pretty chill in the basement.
There's Tuba if you like the tanned look and huge muscle heads dancing on the bar shirtless.
Alcatraz is mostly hip hop, but an ok place.
Valhalla is rock/gothic
Morphine is worth checking out for live music
Maybe you can take her for Italian food (sth different ) There's a nice place called Figaro or a Greek place called Mykonos which has pretty good food.
