Express Bus Terminal Underground Shopping Mall, Goto Mall is the largest underground mall with over 600 stores in Seoul. The 880m long alley is a shopping heaven and a favourite for many shoppers, particularly women. There is rarely a day where the hustle and bustle inside the mall is not at peak levels. Be it weekdays or weekends, the mall rarely experiences empty alleys. The amazing thing about the stores in this shopping complex is that they are not huge areas individually, but still manage to provide variety of products. I mean it when I day, there is no shortage of different designs, colors and what not in the mall.
