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"

This nearly 200-year-old bar— reputedly the oldest in Barcelona, is an absynthe bar. Was one of the locations from Vicky Christina Barcelona's film. The Marsella is one of those places that Hemingway supposedly loved to frequent (Hemingway being to bars in Spain what George Washington is to inns in New England).

I always love to observe people in the city at the open space cafe like Federal. Their breakfast and coffee are amazing!

Chocolateria Churreria

It is a charming and welcome green space in the heart of Barcelona. It has water displays including a beautiful fountain and small lake along with lots of grass verges to lie down and soak up the warm sunshine. A great spot for relaxation, a walk... the place that I like the most is a glass building full of plants inside.
