Osio Tteokbokki is a snack shop on a main street in Seoul that sells tteokbokki in broth and fried mandu. A common way to order is tteokbokki mixed with mandu, with gimmae-gimbap tossed in the broth. Business hours are irregular even on weekdays, and the shop closes around 5 p.m., so you have to go when the signboard light is on. The interior hygiene is poor.
