While in Hong Kong, you should try out this shop which serve very delicious sweet soup, porridge, wan tan mee etc. I never miss out this place when I am there.
The secret of this restaurant's popularity is the refined taste of its food, which turns an ordinary dim-sum or night market item into a delicacy. There are more than 300 items on the menu, including noodles, rice, congee, stir-fried dishes and dim-sum and sweet soups, most of them familiar Hong Kong dishes

Their popularity has lead to them opening shops in Japan and Taipei.
