With all the seafood places in town, you may get a craving for some good meat, and this is the place to go. Both the cooking and the decor suggest the simplicity of the mountain regions near the Aragonese town of Turuel, known throughout Spain for its delicious rustic cuisine. Simple dishes, such as the roast lamb, are cooked perfectly. Do not expect to be wowed with the creativity of the chef or by a chic dining room, but do expect the best beef, pork and lamb in Barcelona. Daily for lunch and dinner. Reservations recommended. $-$$. Most major credit cards. Near the Boqueria market. Carme 28, Raval, Barcelona. Phone 93-302-6789. http://www.rincon-de-aragon.com/cas/index.htm.
