1. Advantages: the labor cost is reduced by nearly 30%. Using electronic menu to search by yourself can reduce the number of some waiters, so the labor cost is reduced by nearly 30%. And the manufacturing cost of the menu is reduced. The use of electronic menus can reduce the use of paper, thus reducing the cost of making menus.

2. Disadvantages: slow response and stuck phenomenon. Ordinary tablet computers have problems such as slow response and too many jams, which will greatly reduce the dining effect. Emotional interaction is reduced. The use of electronic menus in the process of ordering food lacks emotional interaction with the waiter, which invisibly reduces the consumer experience.
