'Alan Yau's gorgeous all-day teahouse serves 150 varieties of tea as well as 24 varieties of dim sum and a range of delicious pastries. Don't miss the pork buns and traditional scones infused with green tea and coconut,' says Matthew. 'The glass cabinets of exquisite petits gateauxmake choosing a cake like shopping for an expensive ring,' adds Tonia. 'They have a dizzying selection of blue teas, including the high mountain oolong, a semi-fermented tea, which offers a delightful balance between the freshness of a green tea and a maltier black tea. They also carry vintage pu-erhs, which go up to 35 years old.'
