HeyDay Cuisine is a popular Cantonese restaurant and banquet venue with several outlets across Hong Kong. The 'big brother' char siu is a winner. However, the Kwun Tong branch is especially loved for its early dim sum service at 7:30am. Known for quality ingredients and affordable luxury, its must-tries include barbecue pork buns, cheung fun, baked pork buns, custard cake and flaky radish pastries — favourites that keep diners coming back.
