Here's what a sports fan wants — nay, needs — in a good sports bar: good food, reasonably priced alcohol, plenty of screen visibility, and a crowd that doesn't make the entire thing painful. It sounds like a simple formula, but it's almost never done right. Duffy's, a Florida-based chain of fan-friendly bar and grills, is catching on, though. The location just off SE 17th Street in Fort Lauderdale, in a building that used to house a steak joint, features a bar surrounded by giant flat screens hanging overhead like glowing altars to gods of sport. The menu is also diverse, with everything from glazed ribs to burgers to decadent nachos to goat cheese salads. And the regulars are generally above drunken obnoxiousness but not above giving a stranger a high-five when the home team scores.
