(some) of my favourite restaurants:

This a list in progress in no particular order. The list is updated regularly on Google Maps: 

Brevet CC. Sant Cugat del Vallès. Barcelona

Disclaimer: I can't be impartial. I'm one of the owners. Sant Cugat was missing a nice place, with excellent coffee,  good quality healthy food and cycling friendly. And we made it.  

Space: 9/10.  

Service: 9/10

Food: 9/10

Price/Quality: 9/10

Bar Cañete. Raval. Barcelona

Don't let the "bar" prefix fool you. This is a premium place for excellent food in small portions. If you can, reserve a place at the bar counter so you can also enjoy the cooking process.

Bar Europa. Mataró. Barcelona

The kind of places I love the most. Under the radar, ugly place with awesome quality food. Best "Calamares a la romana" you can eat. Fresh seafood. Great Service.

Vaso de Oro. Barceloneta. Barcelona

L'empordanet. La Tallada de l'Empordà. Girona
