As we all know, in the catering industry, if you want to run a good store, there are many repeat customers. One is taste, and the other is service. As long as these two points are done well, the customer's return rate is unreasonable. Therefore, to sum up, in order to make money when opening a restaurant, apart from an external factor (such as the location of the store, the flow of people, etc.), there are only product tastes and store services. As long as these points can be achieved, your store can't think about it, let alone the monthly income of 31,111, 41,111, and 51,111 or 61,111 is not a problem.
