Sticky fingers is more like a basic rock club. They've got some decent gigs there every now and then but it's, from what I've heard, more a place where all the cool kids go when they want to feel wild and alternative. However, I'm sure you'll always find some dude there in some corner trying to look misantrophic while he really just wants to get laid. But overall, I think there's a pretty mixed crowd there.
Other than that, there's
Belsepub at Kompaniet,
Club Nocturnal at Cronan, Metalterrassen at Henriksberg - and Rockbaren of course as you already know...
However, those are all just sort of theme nights on normal clubs, arranged at a pretty irregular schedule so it's kind of hard to say if it's worth going somewhere depending on the day you're in town. I mean, I'd rather sell my total collection of records than walk in on Kompaniet on a Thursday when they've got some kind of synth theme going on there. I think Belsepub has got fridays the first and third week in every month or something like that, Club Nocturnal is usually on Saturdays but they've got more off-seasons. Metalterrassen is arranged like, once every month, I've never been there and I can't until like, 2005 due to the age limits they've got there (20).
But hey, that's just if you want metal in your ears while you're getting drunk so to speak. Uhm, guess you could go out anyday on a normal club with normal people who are nice and all that but I can't really see the point in that. Anyway, as you apparently can read swedish, I'd recommend you to check out
