Kerren, Bilbao

You can be sure you're getting fresh food here because you can watch the chefs prepare everything in the open-plan kitchen. Grilled meats and fish are the specialities and they're best accompanied by fine wines like Viña Vallabona, very reasonably priced at 1000 ptas (EUR 6.01) a bottle. The interior perfectly evokes the style and atmosphere of an authentic old tavern, with bare stone walls lit by old-fashioned wrought-iron lamps. The lunchtime clientele tend to be office workers, but on weekends it's a much more varied crowd.
