Going out in Copenhagen

I am going to Denmarks capital tomorrow and I have some things to celebrate. So I need your help to give me some advice about where to go out, which areas, bars and clubs suit best for tomorrow night. And this is actually a little competition, sponsored by Defshop. They love Stylewalker and offered me a goodie to give away in a little quest, so all of you who help me to find some cool place to go, take part and can win this pants by the Danish brand Humör.

So please, post hints to the best bars and clubs in Copenhagen in the comments, thanks!
