If I had to choose one singular and authentic bar in Barcelona, I'll say "Mendizábal". This is not a fancy bar, and that's what I love of Mendizábal. But it doesn't mean it isn't a cute one with a beautiful decoration and good prices. They have a two very differentiated spaces: one privileged terrace in the city center, and the interior salon. Them both are awesome, and it's perfect because you can decide which one fits better with the situation. They do tapas, sandwich, juices, burgers and veggi burgers. In my opinion, they have the best vegetarian sandwich offer in town. But the most important, you can leave the bar without eating their "patatas bravas"

"Fundació Joan Miró" it's my favorite museum in Barcelona. They do beautiful & interesting exhibitions, but what really mesmerizes me is their architecture by Josep Lluís Sert. It's located at Montjuic mountain but very close to city center, so you can breathe clean air and enjoy art master pieces. The shop and bookstore it's also a place where I can spend many hours.

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