Having to get up at a ridiculous hour to book for this restaurant (two months in advance!) was completely worth it. Tickets was high on the list of must-visit restaurants while in Barcelona and it did not disappoint. Our group of six ordered the surprise menu which was amazing. You simply tell the waiter what you don't eat and whether you'd like more meat than seafood or vice versa, and plate after plate of amazing food, some delicious takes on seafood, others delightful and surprising examples of molecular gastronomy. Highly recommended - if you can get a reservation!
