Just off Sol, in the middle of this hectic ‘high-street’ shopping district, sits Casa Labra – one of the most legendary tapas bars in Madrid. The birthplace of the Spanish Socialist Party in 1879, Casa Labra has lots of charm – if you’re prepared to overlook the slow, po-faced waiting staff (who look ready for retirement and seem to begrudge your every request), and the rather drab look of the place.

As well as the historical significance of Casa Labra, it’s also known for its bacalao (cod in fried batter) and croquetas (creamy croquette potatoes), which are served from the small, original zinc counter in the front room. You may have to queue a while before they take your order, but once you’ve got your drink and tapas you can head out onto the street to enjoy them with the rest of the clientele.
