DIO | Cafe Bar is a cafe bar on Aberdeen Street in Central, Hong Kong, serving single-origin coffee during the day and cocktails in the evening. It also makes cocktails that use oysters and dushier, drawing on traditional Hong Kong food and local liquor. It opens daily from 10 AM to midnight, and the bartender asks your preferences, explains the menu, and recommends a matching cocktail. Seating is limited, so it gets quite cramped when busy.
