(Tied with Via Matta) In replacing their much-loved UpStairs at the Pudding (some considered it the real institution of Harvard Square), Deborah Hughes and Mary-Catherine Deibel had big shoes to fill—their own. But they've done it, creating an outstanding restaurant that has surpassed the expectations of even their most loyal following. The décor is at once outrageous and glorious—plaid patterns on the walls with animal-print carpeting, jewel-toned upholstery, massive fireplaces, gilded mirrors, and lots of pink. Two menus, in the hands of chefs Susan Regis and Amanda Lydon, offer everything from simple grilled cheese and rich tomato soup to flavorful Kumamoto oysters, roasted lamb, and rabbit. Don't miss the "wedding cake for one" dessert: The portion is large enough to share, but this is a divine indulgence for you and you alone.
