In 406號號地下, Hong Kong, Keung Kee is best approached as a street food restaurant: specific enough to guide expectations before you book. The draw is the kitchen's clarity, hospitality and consistency; at a casual value price point, it should be judged as a practical, value-minded stop with more character than a default booking. The Bib Gourmand signal is useful because it shifts the question from luxury to value, personality and the pleasure of a meal that feels generous for the spend.
