Tasty coffee and jamon pintxos.
"Founded in 1927, La Viña retains its charm and quite a few original furnishings and fittings; letters sent from travelling Basques to the stamp-collecting founder, Bautista González, cover the walls. This was a taberna for tertulias, gatherings of artists, writers, philosophical drinkers, and for jamón. It still is. Hugely popular and always packed, the bar’s speciality is slithers of acorn-fed Joselito jamón, though good raciones (plates to share) and media raciones (half plates) are available. Now run by Bautista’s grandchildren, la Viña has expanded next door to include a deli, and more formal restaurant."
