Dongbei is a Chinese restaurant in Seoul that serves lamb skewers and Chinese dishes. The lamb skewers are grilled with simple seasoning, and the meal comes with spicy jjajang, guobaorou, and egg soup. It is also open for lunch, and many customers drink Yantai with their meal. When group dinners overlap, seating arrangements and the status of ordered dishes are disappointing, and service responses are not smooth.
