Punk rock, mohawks, and a burger-eating contest. Sounds sweaty, but if you like your music loud, this is a great chance to catch the best this city has to offer. The 4th annual Burger Fest returns with 32 bands on two stages at the Japanese Hall (487 Alexander) this Saturday (Aug. 16). Music starts at 1pm; tickets $10 at the door. Oh, and the burgers are organic and hormone-free, if that was holding you back from stepping into the Burger Dome.
