Fodor's Expert Review Les Voltes

Built into the vaults of the Roman Circus, this unique spot serves a hearty cuisine within one of the oldest sites in Europe. You'll find Tarragona specialties, mainly fish dishes, as well as international recipes, with calçots (spring onions, grilled over a charcoal fire) in winter. (For the calçots when in season, you need to reserve a day—preferably two or more—in advance.)
