Can't say for certain, just try around the Barfly, Zanzibar, and Bandwagon and so on - there's usually something good happening around there (or at least, there used to be), although they might be turned over to DJ's on Friday now, I can't remember it's been a while!
Also, Gigwise is a pretty good online resource:
http://www.gigwise.com/And if you're in town, try and pick up a copy of The Fly for free, it's got detailed gig listings in and around the area.
