In a top class restaurant, it is very important to give the best possible service to the customers. Customers usually have higher expectations of service when the restaurant is known to be top class and believe that the service staff should go above and beyond their expectations by constantly surprising them and delighting them with excellent service. The top class restaurant have excellent training for their staff and they make sure that the service is never below an acceptable level. There is a lot of work that goes on behind good service. In a restaurant, one of the most important aspects of giving first class service is to never get behind. That is true for the kitchen, too; because if the chef gets behind on preparing the food, the waiter will get behind on serving the food. An excellent service staff may get behind, but they work together to catch up and not get behind again. One of the most important things is that the restaurant is not understaffed. When a restaurant is understaffed, even by one or two waiters or chefs, the service will be below par. When people eat at a luxury restaurant, their expectations are much higher because they are paying above what they would pay in a mid-range restaurant. Just as the old saying goes, you get what you pay for; people want more when they pay more.
