Even if you can't afford to buy the designer threads or artworks in the many boutiques and galleries of Apgujeong, it can still be fun to browse. Garosu-gil, one of Gangnam's most famous strips, is worth a stroll for brand-name stores, cute fashion boutiques and budget accessories aimed at students, plus art galleries, restaurants and cafes. Head to Lotte World Mall if you want to shop in the country's tallest building; and to COEX Mall if you want to get lost in the maze of stores in the largest underground shopping complex in the world.
