Seongdeok is a Chinese restaurant in a Cheongdam-dong alley serving Hong Kong-style dim sum and Chinese dishes. The menu spans dim sum such as shumai and guchae-gyo to guobaorou, mala xiang guo, and tomato egg rice. A room seats six to seven people, and the space is set up like a Chinese tavern where diners pair the food with gaoliang liquor. Lines at weekday lunch are long because of its popularity.
