Crystal Jade Sogong is in the basement of a building behind Lotte Department Store Avenue L in Myeongdong, Seoul, and serves Cantonese Chinese dishes adapted to Korean tastes along with dim sum. The menu includes shrimp gyoza, truffle shumai, and jajangmyeon with Iberico steak. The dining room is large and has private rooms, so the layout suits group gatherings and company dinners. The dim sum wrappers are sometimes sticky.
