Quiz U Iz or Quiz U Ain’t won at Nick’s Wednesday night, knocking off the Power Play, 86-78. But the big story was Nick’s change of bartenders. Joe, an Olde City legend, was recently traded to Houston for Yao Ming. “Yeah, Ming isn’t quite as polished as Joe was, and he doesn’t speak real good English, but he can easily snag bottles off our top shelf,” said bar owner Nick R. Beef. Nick’s also got a 2005 2nd round draft pick in the deal.
