Guinness World Record Approved, Sobrino de Botín is the oldest eatery in the world. Serving up traditional Spanish cuisine since 1725, it specializes in cochinillo asado (“roast suckling pig”) and sopa de ajo (an egg, poached in chicken broth, and laced with sherry and garlic). It is said that Francisco Goya worked as a waiter in this very restaurant while trying to get into Madrid’s Royal Academy of Fine Art. Ernest Hemmingway, who frequented many restaurants and bars in the area, also mentions Sobrino de Botín in his novel, The Sun Also Rises. If you would like to enjoy a meal here on your trip to Madrid, make sure you call and make a reservation; they book up fast.
