About Baster
Baster is a tight, high-energy tapas bar in Casco Viejo where homemade vermouth and impeccable small plates define the experience. The tortilla individual—made fresh to order with just potato, egg, and salt—has earned a devoted following; reviewers consistently praise its juiciness and authentic preparation. The calamari sandwich and brioche de albóndigas showcase the kitchen's care for original pintxos, while the wine list, beer selection, and cocktail programme all punch above the bar's intimate footprint. Staff are notably warm and attentive, remembered by name across reviews. The space is small and fills quickly, especially during lunch and dinner service, but the atmosphere remains informal and welcoming. Breakfast and coffee are strong draws, with a quality espresso programme and a house vermouth that reviewers call the best in Bilbao. Wheelchair-accessible entry and interior space accommodate mobility needs.
