SALAMANCA. Founded in 1963, this is traditional Basque at its best. Great cream of crab soup, grilled shrimp and brill in a green sauce are just a few of the specialties Alkalde has been serving for decades.

ATOCHA. The original owner, a bullfighter, took the tapas bar's name in honor of his son who was killed in the ring. The walls still display bullfighting paraphernalia, and the conversation within often turns to the best bullfighters. You can order from a slew of different tapas, including garlic soup or smoked fish montaditos and the salad comes free with your drink. The friendly environment is sure to please. METRO: Tirso de Molina

Don't be surprised if you run into royalty while dining at this elegant restaurant. For an upscale snack, come try the fresh vegetable flan or vichyssoise. The specialties include duck liver and codfish. The service is as good as the food, making the whole meal a delightful experience! Metro: Ópera

CENTRO. Casa Labra has special historical significance because the Spanish Socialist party was established here in 1879. When you enter, you'll get the impression that the dark wood interior and Spanish-style décor appears to have changed very little over the past 100 or so years, and this just adds to the tavern's charm. Even today, the restaurant still maintains a special place in the hearts and of Madrid's locals and visitors. In addition, their stomachs do not forget its great tapas menu and traditional Spanish cuisine that features cod fritters. METRO: Sol.
