Namgi Guksu is a Chinese restaurant in Aberdeen, Hong Kong, serving rice noodles topped with fish balls and meat. It offers spring rolls, spicy pork, and a choice of sour or mala broth. The noodle portions are large, and the dining room is up a flight of stairs, so seats fill quickly when the restaurant is busy. The entrance is not easy to spot, which makes it hard to find on a first visit.
