To my taste, the best restaurant in town at all levels: the food is exquisite, they have a large traditional Catalan menu, the service is excellent (waiters know the menu and the wines very well), and the decoration is carefully thought out, taking us to the old times of Catalonia. I have been there quite a few times and it's perfect every time.
It's an old masia—a Catalan farm—converted into a restaurant. It explains the decoration on the picture. There are several rooms, smaller and bigger, to host different type of events. In summer, you can enjoy the very romantic terrace with its candles.
Count 50 € per person as a minimum.
