El Bulli is possibly the most talked-about restaurant in the world today; this Michelin-rated establishment sits on the coast of Catalonia in Barcelona, and specializes in startling gastronomic experiences.
Chef Ferran Adria is utterly devoted to his craft and the mad scientist of gastronomy actually spends most of the year in his food laboratory concocting the menu for El Bulli's open season - May to September.
Dinner is an extraordinary experience, occasionally exalted and frequently frustrating: diners are cossetted like guinea pigs, their reactions scanned by the maître d' and the great Ferran Adrià himself.
Place a reservation in October for the following year and keep your fingers crossed.
