High in the iconic Palacio de Comunicaciones on Plaza de la Cibeles, this much-loved restaurant by Adolfo Muñoz takes Spanish staples, gives them a twist from the Castilla–La Mancha region, and then riffs a little wherever the urge takes him. Dishes might include rice infused with saffron, vegetables and manchego cheese, or pig's trotters stuffed with onion and wild mushrooms.
The views are lovely, and the attached cocktail bar likewise.
