Casa Botin
Sunday hours: Sunday, 13:00–16:00 and 20:00–24:00
Casa Botin opened in 1725 on Calle de Cuchilleros 17 and the Guinness Book of Records certifies it as the oldest restaurant in continuous operation in the world. The wood-fired oven has never gone cold, and the cochinillo asado, the suckling pig roasted until the skin shatters, is the one order. A full lunch lands around €50 to €75 a head. It runs the longest Sunday of any heritage room in the city, full lunch and full dinner, and the cellar tunnels below are a piece of old Madrid worth the climb down.
