6. Redhead Piano Bar

Location: 16 West Ontario St.
Website: redheadpianobar.com

Aside from being the best piano bar in town—with décor invoking the classic nostalgia of old Hollywood, and bartenders who know how to pour—you'll also find another late-night phenomenon most Tuesdays. Hold out until 2 a.m., and the musicians from the Underground Wonder Bar pile into the Red Head to jam until dawn.
