How to calculate the cost of Chinese restaurant in hotel?

Chinese restaurants mainly provide catering for individual guests who come here to stay. There is a balcony and a living room. Banquet living rooms are generally used for wedding banquets and conference meals, with dozens or even hundreds of tables. Waiters in China usually prepare meals, serve them during meals and finish their work. I listed several common specific tasks: preparing the tablecloth for dinner, soup roots and money, serving food, pouring wine and vegetables during dinner, clearing the table after dinner, and finally resetting the table.
