If you're a serious shopper with only enough time to visit a single mall, make it this one. Resident fashionistas favor Paseo Alcorta for its mix of high-end local chains and boutiques from some of the city's best designers. Trendsetters such as Jazmín Chebar and Allô Martinez make cool clothes for women, while María Cher and Chocolate offer more classic chic; the men can hold their own at Etiqueta Negra and Félix. The international presence is strong, too, with stores like Swarovski, Lacroix, Cacharel, and Zara, as well as the usual sports brands. There's even a personal-shopper service if it all gets too overwhelming. Complimentary hotel transfers, free Wi-Fi, and a classy food hall give you further reasons to drop in.
