Manna One is a traditional Chinese bakery in Manhattan's Chinatown that sells Hong Kong-style breads, cakes, and coffee. It serves egg tarts, pineapple buns, char siu buns, and Hong Kong-style milk tea, all baked in-store each day. The shop has been open for more than 25 years, and the coffee is made by hand by a barista. Pastry selection is largest in the early hours, and staff rush customers in a manner that is rude.
