Fodor's Expert Review Chicago Cultural Center
Built in 1897 as the city's original public library, this huge building houses the Chicago Office of Tourism Visitor Information Center, as well as a gift shop, galleries, and a concert hall. Designed by the Boston firm Shepley, Rutan & Coolidge—the team behind the Art Institute of Chicago—it's a palatial affair notable for its Carrara marble, mosaics, gold leaf, and the world's largest Tiffany glass dome.
