La Alcoba Azul
One of Barcelona's most beloved bars, La Alcoba Azul offers a wide selection of tapas with a full-on immersive atmosphere. The decor reflects the Moorish influence of Andalucía mixed with the quirkiness of the original owners, so you'll get illuminated lanterns and broken birdcages hanging from the ceiling, while a years-old candle burns in a corner. In case you can't get a table here, try one of their sister restaurants a couple doors down, La Alcobita.
