Hola! I live now for about 1,5 years in Barcelona, and during this time I went to quite a lot of brunch places. It is one of my favorite things to do in my free time with my friends. Barcelona has so many Brunch spots and still there are a lot opening new places. So you will always find a place you haven’t been before.
Here are my top 5 favorites:
Brunch & Cake
Brunch and Cake has a few different locations, and all are very good. But my favorite is the one in Barrio Gotico: Passatge Madoz 6. This one is located at plaça Reial, which is a beautiful square in the old part of Barcelona, filled with restaurants. It is definitely worth checking out.

Lulu & Flyn
Lulu and flyn is located in El Born, they have seats inside and outside. It is also a good place to work or study. Tip: try the Loaded scramble, it is my favorite.

Lilo Brunch is also located in the neighborhood Eixample. It is a nice location, I am in love with their pancakes, you can also sit outside and it is the perfect location for people watching 🙂
