Despite its name, the Manhattan Inn is the piano bar for the Brooklyn set, and it manages to update a classic concept. With a rotating cast of accomplished musicians taking requests, and an impressive lineup of innovative cocktails, the five-year-old Greenpoint bar and restaurant is a classy spot for the cool cats outside of midtown. Maybe the most unusual aspect of the joint is that patrons aren’t mere onlookers. On Tuesday nights, the bar hosts piano karaoke, giving you the opportunity to sing along with live renditions of your favorites. The restaurant boasts a full menu — and the kitchen stays open till 11 — so there’s little chance of going hungry while soaking up the sounds.
