Fodor's Expert Review Starfield COEX Mall

This sprawling complex is more than just a shopping destination: it's the mothership of trendsetting fashion, food, culture, and entertainment in Seoul. The largest underground mall in Asia, COEX is home to shops carrying national and international brands, as well as restaurants serving cuisine from around the world, plus a movie theater, an aquarium, and the Starfield Library, where you can browse through thousands of books or just relax under the skylight roof. It's a great place to lose yourself for a couple of hours, and when you feel like coming up for air, make sure to stroll along the grounds outside and check out the giant golden sculpture of Psy's hands as he does the "Gangnam Style" horse dance.
