Burger King and McDonald’s franchises stand near the Reina Sofia, but Spaniards snub them in favor of the equally fast but more varied sandwiches at El Brillante. The finger-sized 4-inch mini-bocadillos make a terrific snack, while the 10-inch super bocatas are a meal. You can get everything from sliced pork with roasted peppers to an omelet sandwich, but El Brillante is acclaimed for its fried calamari rolls. Tables are few, but there’s a certain style to eating while standing at the stainless steel bars, letting your spent napkins float to the floor, just as the Spaniards do. Taking half a city block, El Brillante has a door on the Carlos V roundabout and another on the plaza in front of the Reina Sofía.
