While it’s exceptionally difficult to get a reservation here, you should at least try. Tickets is the closest you can get to El Bulli (the now-closed restaurant that was once considered the best in the world), and is the flagship Barcelona restaurant from the head chef, Ferran Adria, and his brother. Tickets is standard tapas style, a bit gussied up. The restaurant is circus-themed and there are several stations around the two dining rooms that are responsible for producing one dish or another (though the food will be served to you at your table). If this sounds like a fun place, that's because it definitely is.
