Chai 797 Gimpo Lotte Mall is a Chinese restaurant in the basement food court of Lotte Mall Gimpo, serving jjajangmyeon, jjamppong, and tangsuyuk. The menu also includes shoronpo, mandu, bokkeumbap, and haemul jjamppong, while the gogi jjamppong comes out spicy. It sits inside Lotte Mall near the airport, so it draws a fair number of customers. The jjajangmyeon and tangsuyuk portions are on the small side.
