El Bulli Hotel - Hacienda  Benazuza.
Possibly the best small hotel/restaurant in the world (closed - may reopen, possibly as soon as 2013).
 Ferran Adria directs the Michelin starred restaurant at Benazuza which presents from the back catalogue of El Bulli. The "degustacion" breakfast was a new and fascinating experience. (expensive, formal - gentlemen are asked to wear a jacket, although few actually do).
