It's all relaxed elegance here, beginning with the fine selection of appetizers at Senhor Antonio Tapas and Wine Bar and continuing through the French doors to the dining room, which has polished wood floors and plum-velvet armchairs. The exquisite fish, which form the menu's base, are flown in from the Azores and Madeira. You might have monkfish, grouper, or peixe espada (scabbard fish). Traditional Portuguese dishes include assorda, in which seafood is folded into a thick, custard-like soup made with bread and eggs. But there's much for meat eaters, too—like a roasted rack of lamb which sparkles with Douro wine sauce.
