El Sobrino de Botín

The world's oldest restaurant (with a signed Norris McWhirter certificate to prove it) is still coming up with the goods after nearly 300 years. For all its popularity as a tourist destination, its nooks and crannies add up to an atmospheric – if cramped – dining spot. Botín turns out great roasts, including that old Spanish favourite, 'cochinillo' (suckling pig). The 'cordero' (lamb) is also superb, as are the house-named 'almejas' (clams). And, yes, seeing as you asked, Hemingway did come here.
