According to the different price forms of menus, all menus can be divided into three types: ① zero menu; ② Package menu; ③ Mixed menu. Among them, zero menu is the most common and widely used menu form. The price form of a la carte menu is that every dish is marked with a price. A la carte menu has many price grades, which can meet the requirements of different levels of guests; Set menu set menu is commonly known as company food, also known as harmonious food. A package is a package with a fixed price. The price of the set meal is also based on the whole meal, not on a single dish; Mixed menu combines the characteristics and advantages of a la carte menu and set menu, but the main disadvantage is that the menu is too large and inconvenient to use.
