RESTAURANTS

 Quimet and Quimet:

Quimet  and  Quimet is a family business that has been passed down from generation to generation. 
The walls are lined with bottles of alcohol, it's a place just for standing, but their tapas (bread with some special complement) are a delight.

La Cova Fumada:
It is low price, but this small and lively place of tapas always brings together a crowd.
The secret? Delicious octopus (octopus), squid, sardines,. 
Everything is incredibly good.
