Joss Tteokbokki in Gangnam is a snack shop that serves tteokbokki, fried items, and sundae. It offers a one-person set and a tteok-twi-sun set, and both students and parents eat there. The owner handles the register, cooking, and takeout alone, and tables clear quickly even though the space is small. The tteokbokki is strongly spicy.
