Chaimonster is a Chinese restaurant on Bulgwangcheon-gil in Eunpyeong-gu, Seoul, serving jjajangmyeon, jjamppong and other meal dishes alongside tangsuyuk. Diners can order both meal and main dishes together, from jjajang and jjamppong to tangsuyuk and chili shrimp. Orders are placed through a QR code at the table, and a mini bowl of rice is free on request. There is a wait during peak hours, and the food tastes good but the portions run small.
