Gui Leng Kao
This is a Gui Leng Kao, a type of herbal jelly. I learn to like this jelly stuff 10yrs ago. Will go for it when ever I am near to one of this store.
Opp… I only snap below photo after I have a few scope on yesterday evening. 
Actually it taste bitter… according to the formula… this jelly can made our body less heaty.
Usually people will add in some honey + sugar into the jelly to reduce the bitterness.
Koong Woh Tong is one of the company which open a few branches in the city. The one I visited last night is located in Mid Valley.
