Restaurante Botín

Founded in 1725 and Guinness-recognised as the world's oldest restaurant, Botín still roasts cochinillo and lamb in the original wood-fired oven across its warren of tiled, beamed rooms near Plaza Mayor. Approached as a one-time historical pilgrimage rather than a regular table, it earns the trip on heritage and the integrity of that single dish. Book the suckling pig, and treat the visit as a piece of culinary history.
