whats up in sthlm?

[El president]

I`m in sthlm a weekend from 22. sept - 24 sept. Does anyone know if there is something extraordinary exiting happening in that date? I have read the past sthlm treads, but are looking for a nice place to go dancing until 5 in the morning. Not too flashy. I dont like the whole stureplan scene. A underground rave/house happening would be very cool, or a simular hiphop happening. anyone know?

And I would also be looking for some nice second hand shops. Any suggestions?

Could anyone recommend me a descent but cheap place to eat?

And something to do that I could only do in Sthlm. If that is.

Peace
