Solito Taquería Mexicana
Some of the best tacos you can gobble down in Madrid are found, improbably, in tourist central, just off Plaza Mayor. There are also pitch-perfect classics like cochinita pibil (slow-roasted marinated pork) chalupas, huitlacoche quesadillas, and pozole (choose from three types), as well as real-deal margaritas and cajeta (caramel) crepes. Outdoor tables with heat lamps are available for those who book ahead.
