Ferran Adrià is considered by many to be the greatest chef in the world and his restaurant, El Bulli, to be the greatest restaurant in the world (if such a thing exists). Located in Roses, Spain, El Bulli is a holy mecca for food lovers. The 35-course taster's menu is a grand experience of tastes, textures, and wonder. An architect of molecular gastronomy, Adrià's creations are designed to surprise and enchant his guests. Here are some photos from the restaurant. Notice the contrast of the highly modern kitchen with the Old World European style of the dining area.
If you go, plan on making reservations months in advance. El Bulli serves only dinner, has less than 50 seats, and only makes one sitting. They are also closed from October to March. Of the approximately 2,000 bookings every year, they receive over 400,000 applications. Expect to pay about $150 per person (a steal!), not including wine.
