Used to be one of my fav bars :) there are 2 locations, both good

Head up to the rooftop for Drinks and Tacos with great views of the city. 

Salvador Dalí often visited Cadaqués in his childhood, and later kept a home in Port Lligat, a small village on a bay next to the town. A summer holiday here in 1916, spent with the family of Ramon Pichot is seen as especially important to Dalí's artistic career. Other notable artists, including Pablo Picasso, Joan Miró, Marcel Duchamp, Richard Hamilton, Albert Ràfols-Casamada, Antoni Pitxot, Henri-François Rey, Melina Mercouri and Maurice Boitel also spent time here. Cadaqués is mentioned in the story "Tramontana" by Gabriel García Márquez.

I only recommend walking around the Barceloneta beach at sunset, there are fewer people and in the fall and spring seasons is very nice to sit on a terrace watching the sea and entertaining yourself with the activities of the area.

One of the most special buildings of the city
