Hyojadong Yetnal Tteokbokki sells oil tteokbokki inside Tongin Market in Seochon, Seoul. Customers choose between gochujang and ganjang sauce, and the rice cakes are fried before being coated. John Kerry, then US Secretary of State, ate oil tteokbokki here, and during quiet morning hours the staff say they will add more if the portion is short. The sauce is neither spicy nor salty, but the flavor is not distinctive.
