Thick plate glass and stainless surfaces harmonize surprisingly well with the ancient stone to create a very upscale look for this modern restaurant in the vaults of the Roman circus. It’s a bit of a circus itself, as it seats 250 people and is popular with tour groups as well as individual travelers. Despite an almost all-tourist clientele, Les Voltes has very good prices for expertly grilled and roasted meats, including lamb shoulder and a spicy casserole of pork trotters. The springtime shellfish assortment is a rather spectacular presentation of shrimp, lobster, and Dublin prawns, but it is expensive (40€ and up, depending on market prices) and requires that at least two people at a table order it.
