Thanks to CS I met those cute couple which whom I've the opportunity to discover some new places in Barcelona. Like this really cool italian restaurant in Barcelona, called Le cucine Mandarosso. Not a typical one: they only prepare pasta and really good cakes. Quite close to Palau de la Música, always crowed (you should make a reservation if you want to eat there).
Raja and Ingrid, I'm very pleased to have met you. I really spent good moments with you ;)
