An entire stretch of stores hawking traditional Korean souvenirs, from tableware to antiques. They also have typical "I love Korea" type stuff such as keychains and t-shirts. There's an interesting mall called Ssamziegil in the area, which is designed in such a way that going through the halls takes you to the top floor without climbing any stairs.
