Fodor's Expert Review La Rinascente

Set in a dazzling, seven-story space, Italy's best-known department store is packed topped to bottom with luxury goods, from cosmetics, handbags, and accessories to ready-to-wear designer sportswear to kitchen items and housewares. Even if you're not planning on buying anything, the basement excavations of a Roman aqueduct and the roof terrace bar with its splendid view are well worth a visit. There's also a location at Piazza Fiume.
