Chinese Kitchen Hongseongwon Main Branch is a Chinese restaurant in Seoul that serves dishes such as chadol jjamppong and jajangmyeon. The chadol jjamppong contains a large amount of chadol and bean sprouts, and the portion is large. It has many private rooms, so families and company groups go there, and rice dishes come with egg soup. At lunchtime people crowd in, so those who arrive late have to wait for a table.
