IFC Mall
This polished mall is set in the three basement levels of the International Finance Center Seoul and is connected to the subway station via an underground walkway—a real godsend if you’re visiting Seoul during a frigid winter or the dog days of summer. While the mall features a pretty standard lineup of coffee shops, fast-food eateries, and cosmetic and fashion brands, it’s also known for its sleek 4D theater with lie-flat seats.
