Barcelona is also amazing because of it's surroundings in winter I love going to the mountain, it's just one hour and a half drive and in summer to the beach of course.
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.
Picnic is a restaurant located in the Born neighborhood. A welcoming environment, pampering every detail. The best brunch in Barcelona. A great team of different countries and knowledge of the world of food and wine. They change the menu every season, looking for fresh products to make family recipes and creative dishes from different parts of the world.
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.
