Concierge.com's insider take:
Parisian architect Jean-Paul Viguier designed the unique, Swiss cheese-like structure that houses the Sofitel. Just two blocks off the Magnificent Mile, this Gold Coast sophisticate hosts business travelers and Euro movers and shakers with its seductive lobby and 415 spacious rooms. Each has a marble bath and plenty of perks, including Web TV, two-line phones, high-speed Internet, and designer toiletries. The property's Café des Architectes serves excellent New French cuisine.
