If you find yourself in traffic in the middle of the night, you are likely near Dongdaemun Market, as it is open 24 hours a day. The powerful appeal of Dongdaemun stems from the fact that you can buy everything you need at a reasonable price, in one convenient location and anytime. The market is full of small stores selling their products on the street as well as several larger structures like Doosan Tower which houses hundreds of separate stores. This spot is popular with Americans because it offers a tax refund system enabling foreign tourists to claim a ten-percent refund on goods they purchase here.
