An outpost of an Arizona-based steakhouse chain, the swanky Mastro's is a major player in the Chicago steakhouse scene. The River North spot sprawls across two levels and features a menu of more than 15 steaks and chops, plus inventive martinis and a see-and-be-seen piano bar. The creamed spinach and baked potato sides are absolute classics.
