Jahason Mandu is a mandu restaurant on Bugaksan Skyway-gil in Buam-dong, Seoul. Its pyeonsu includes cucumber, and its nokdujeon comes in a plain style with almost no seasoning taste. It is a 15-minute bus ride from Gyeongbokgung Station Exit 3, and the full-window seats look out onto Inwangsan. On weekends the wait is long and the parking lot is small.
