This is one of my top 10 favorite restaurants in Durham, NC. To me, it's most important that a restaurant have (a) unique character or charm and (b) lovingly prepared, amazing food. Hong Kong Chinese has both.
I agree that the service is adequate at best, but one simply shouldn't hold authentic Chinese wait staff up to the usual U.S. standards. Instead, just take it as it is.
This restaurant is a gem, and if anyone doesn't agree, that's fine -- it just means more delicious food for ME! :) I eat at Hong Kong as often as I can!
