Jack Dweck: Get your ticket online the day before. It sells out quickly.
Jack Dweck: Best and biggest club I've ever been to. Go just to see it! (Clubs don't really start until 2AM here)
Santi: Best tapas. Tiny place. No seating. Authentic and traditional. Family owned. A must-go. Check hours (it's not a touristic area)
Santi: By far, the best "patatas bravas" in Barcelona. Worth it. Again, not a touristic area.
Santi: Hospital by Gaudí. Beautiful. 1 stop from Sagrada Familia. Seven years ago was still open as a hospital. Today you can visit it.
Santi: "elBulli", best restaurant in the world by Ferran Adrià closed in 2011 and their three main chefs opened "Disfrutar"
