Sogong Underground Shopping is an underground mall along Sogong-ro in Seoul, connecting to buildings such as City Hall, hotels, and the Bank of Korea. Shops there sell souvenirs and K-pop albums, and the mix of stores is varied. The underground passage takes about four to five minutes to walk, and its 11 exits lead to major buildings. It runs beneath main roads and intersections, so walking here follows a different route from the street above.
