A bar is a licensed establishment where alcoholic beverages are served. It typically features a long counter with bottles and glasses on display behind it. Bar stools or seating are provided. While service is formal, food options are usually limited to snacks. The bar contains a front area where customers order, a back display area showing available drinks, and an under-counter storage and equipment space. Proper planning considers factors like location, size, layout, utilities, hygiene, and necessary equipment.
