THE UPTOWN 8904 Aurora Ave N, 376-8875 North Seattle has a new rock club, and chances are you don't even know it exists. The Uptown, hidden away on Aurora Avenue between car dealerships and motels, hosts both local and touring rock bands, plus it has pool tables and dart boards, a full menu, and for those who like their rock with a little whiskey, a full bar. No, it's not gonna give Graceland a run for its money, not yet anyway, but the Uptown might help North Seattle fill that void when it comes to having decent (or any) rock venues. MEGAN SELING
