Some of the pintxos (Basque-style tapas) here are remarkably creative, such as the fig, goat's-cheese and orange-mousse rusk (€2.90). Peruse and order from the preprepared selection then consider moving down into the cellar room with its part-exposed brickwork, or on to the canal-side summer terrace.
Or just sip a beer and wait to see which warm offerings come around. Prices are calculated by counting colour-coded sword-sticks.
