What are you going to do for western food, the kitchen or the waiter? If it is a waiter, it depends on the business and grade. If the grade is higher, it will be more formal and cooking will not be very hard. Just more rules (there are some rules everywhere). When you first go, you will be familiar with the meal content and ordering skills as soon as possible, and you will be arranged to eat slowly. Working hours are generally divided into three classes (morning, middle and evening classes), usually eight hours, three to four days off in January, and holidays are counted separately.
