Oualidia is famous for its oyster beds, which produce about 200 tonnes of oysters annually, and this restaurant attached to an oyster farm is a great place to slurp some bivalves. These come in three grades, with the difference being the size. Order them grilled, served with almonds or au naturel. Paella and fried fish are also available.
The well-signed access road to the restaurant is off the main highway, at the entrance to town. It's an easy 15-minute walk from the roundabout in the upper town.
