I really don't think Yung Kee is overrated at all, as the goose quality is much better than other restaurants, and not as greasy. I tried over 200 restaurants serving goose in HK, and none would compare to Yung Kee. Beside, you have to order their special goose. They would not have been chosen as one of the best restaurants in HK, if their food is just average.

Also what makes Yung Kee the greatest is it's consistency, other restaurants might be a hit or miss experience.
