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.
I first came to this store, bike and barber shop to photograph its owner, a well known rapper from Barcelona. It's a nice place to find some good hip-hop classic records, buy a bike and also have your beard or your hair shaved.
Simple and charming, Bacaro is an authentic Venetian tavern located near the rear of the Mercat de la Boqueria, where its owners buy daily the freshest products to create an excellent menu featuring always homemade pasta and fish dishes. Definitely a great alternative to enjoy non-commercial Italian cuisine.
After waking up on a lazy saturday I love going to La Boqueria market (Mercat de Sant Josep) to buy some vegetables, fruits, fish to set up a nice lunch at home.
