Once a humble street stall in 1979, Kai Kai Dessert is now a Hong Kong Bib Gourmand–recommended spot. Its Causeway Bay branch continues the tradition of classic tong shui – Cantonese sweet soups and desserts — from red and green bean to black sesame, sweet potato and ginkgo barley with beancurd. Ingredients are meticulously sourced, including fragrant Zhanjiang black sesame, crisp Guilin water chestnuts and Italian barley, all served with neighbourhood warmth.
