El Xampanyet

The eponymous bubbly is actually a pretty low-grade cava, if truth be told, but a drinkable enough accompaniment to the house tapa – a saucer of Cantabrian anchovies. Lined with coloured tiles, barrels and antique curios, the bar chiefly functions as a little slice of Barcelona history, and has been in the hands of the same family since the 1930s.
