Hong Kong Style Dessert - Red Bean Soup

I like Hong Kong Dessert. As far as I know, there is only one Hong Kong Style Dessert Shop in Sunnybank Plaza. That is not enough.  I wish there will be more choices. Moreover, we have a number of Hong Kong Style restaurant, why isn’t there a huge demand on Hong Kong Style Dessert? Even a lot of Local Australia have known about out Red Bean Soup.
