Locals regularly pack into this humble, friendly neighbourhood restaurant 1.5km northeast of Plaza de las Monjas for its fabulously gooey tortilla de patatas (potato-and-onion omelette). The tuna (fresh from Isla Cristina) and carne mechada (meat stuffed with pepper and ham) are tasty, too. Arrive before 2pm to snag a lunch table.
Catch bus 6 from the city bus station to Plaza Huerto Paco; walk one block south down Avenida de las Adoratrices and turn left on Calle Villamundaka.
