A good restaurant should charge reasonable prices for food and drinks in order to satisfy customers. Normally costumers have their own reasonable price in their minds for the food and drinks they ordered and level of services they received. Therefore, a good restaurant should also set prices based on the type of food and the level of service they provide as well. The too high price will upset the customers, they well feel suspicious about the quality of the food. These can may cause the customers think many times before they come and visit again.
