Fodor's Expert Review Mesón de Cándido

Beginning life as an inn in the 18th century, Cándido was declared a national monument in 1941, and today displays photos of famous patrons including Ernest Hemingway, Salvador Dalí, and Princess Grace. The suckling pig (cochinillo) is the star; partridge stew and roast lamb are also memorable, especially on cold afternoons. 

Ask for a table overlooking the aqueduct, just a few feet away, and be sure to book ahead.
