Leopard Below, Mirror Above - View this location on map 'Even after the buzz about the Soiree Room at UpStairs on the Square, which opened two years ago (617-864-1933) dies down, the décor will be reason enough to visit. Begin your gawking at the leopard-print carpet and work your way up along the walls, handpainted à la Klimt, and punctuated by huge porthole windows. Finish at the gilded mirror ceiling. Somehow it all adds up to whimsical charm. The food, like the pan-roasted duck foie gras with honey gastrique ($19), can be as luxe as the furnishings, but even the humblest dishes are well tended. A simple romaine salad with sheep's milk feta, olives and orange tomatoes ($12) is astonishingly vivid. '' New York Times 91 Winthrop Street, Cambridge, MA Restaurant
