Truffle Bakery Hong Kong is a Japanese-style bakery in Causeway Bay that sells truffle salt bread, doughnuts, and Danish pastries. Its signature items are the white truffle salt bread and a Hong Kong-exclusive truffle chocolate salt bread, along with matcha cream bread and lemon yogurt doughnuts. The salt bread is eaten cold rather than toasted, and the chocolate version contains a light chocolate cream and small chocolate pieces. A queue forms, so waiting is required.
