Mariwang is a gimbap and snack shop at a corner of the underground shopping arcade on the Line 2 side of Jamsil Station in Seoul. The gimbap selection includes myeolchi, ueong, cheese yubu, and tuna, and spicy odeng and tteokbokki are also available. All food is self-service, and the shop is crowded enough that people are always there when you pass by. Staff responses are brusque and the ordering system is unclear.
