Seongdeok is a Chinese restaurant within a five-minute walk of Apgujeong Station Exit 5, serving dim sum and other Chinese dishes. Yuringi and uyukmyeon can be ordered alongside the dim sum. The dining room is small, so a wait forms at lunch and on weekends, and it was full at 6 p.m. on a weekday evening. The dim sum is on the pricier side.
