Behind the cascading vines on El Amparo's facade is one of Madrid's most elegant gastronomic enclaves. Inside this converted carriage house, three tiers of rough-hewn wooden beams surround tables set with pink linens and glistening silver. A sloping skylight floods the interior with sun by day; at night, pinpoints of light from the high-tech hanging lanterns create intimate shadows. Polite, uniformed waiters serve well-prepared nouvelle cuisine versions of cold marinated salmon with a tomato sorbet, cold cream of vegetable and shrimp soup, bisque of shellfish with Armagnac, ravioli with crayfish dressed with balsamic vinegar and vanilla-scented oil, roast lamb chops with garlic purée, breast of duck, ragout of sole, roulades of lobster with soy sauce, and steamed hake with pepper sauce.
