These two top Cambridge wine destinations are part of a family unit that also includes Central Bottle. Belly, the smaller proper wine bar at the same address as The Blue Room, is known for its narrative list, which tends to change frequently and—channeling Paul Grieco’s psychedelic manifestos at his Terroir wine bars and Hearth—often includes commentary on pop-culture minutiae. (When Mitt Romney made his famous “binders full of women” gaff, Belly responded with a section of the list, under that heading, featuring female winemakers.) The group’s proper restaurant, The Blue Room, is a bit tamer in its approach, but both spots share any easy-to-navigate format, a number of well-selected wines under $50 and enthusiastic, educated staff.
