Founded in 1956, Casa Urola has hefty stone walls, hams hanging above the bar and a blackboard menu chalking up the day's pintxos. Join the lunch and evening crowds flocking for perfectly turned-out bites, such as grilled white asparagus, foie gras with pear compote, hake tacos, and mushroom and Idiazabal cheese tart.
For something more substantial, book a table at the adjoining restaurant (mains €22.50-37.50) and feast on outstanding chargrilled seafood, including wild turbot and line-caught sole.
