City Tavern is the Cheers of downtown. Everybody knows your name. That's because most patrons are downtown residents, especially on any given weekday. As the downtown population has grown from 200 to 6,000 residents in the last 15 years, the Tavern has been transformed by demand into the downtown community center. In May, a group of downtown residents threw their favorite barfly, a decades-long resident of the Manor building, a fund-raiser to help pay for her life-saving surgery. The next week she was back on her favored bar stool sipping a white Zinfandel. The heyday of the historic building housing the two-story bar was some 50 years ago, but the bar keeps that old-timey feel, with its high-backed booths, grainy mirrors and hardwood floors.
