Joaru is a Chinese restaurant next to Exit 4 of Myeongdong Station in Seoul that serves jjajangmyeon and jjamppong. The large seafood tray jjajangmyeon includes shrimp, mushrooms, squid, and chives, and the jjamppong has a rich broth. Food comes out five minutes after ordering, and seats were still available at 11:45 a.m. The dining area is small and long toward the back, so it is not comfortable.
