While carrying out the daily operations of a traditional restaurant, combined with the latest customer flow analysis system, data analysis work should also be done. Moreover, the catering industry is the closest to people's daily lives among all service industries. Improving service quality and providing as good service as possible for every customer who comes to dine is also an important factor determining whether a restaurant can develop sustainably. Install customer flow statistics cameras at all entrances and exits of the restaurant and on different floors to statistically count the current number of diners in real time. Based on the changes in the number of diners, reasonable arrangements should be made for the work of the staff. And according to the analysis of the historical customer flow patterns in the recent period, the quantity of ingredients to be stocked and the staff's shift arrangement should be adjusted.
