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.

Chocolateria Churreria

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

Where the lights come from is the national museum of art in Catalunya. Its an impressive building with great exhibitions and a huge collection of hostoric art. In that area you will also find Mies Van Der Roes house and Caixa forum (Av. Francesc Ferrer i Guàrdia, 6-8).

A great place to find cool books and magazines. Maybe one of the best in barcelona. They also have a space for exhibitions that they often fill with amazing stuff.
