Secondly, food hygiene and quality; catering is a service industry, if the hygiene is not good, may not happen today, but once the problem occurs the consequences are very serious. There is also the issue of food quality, may be the restaurant after some effort to play their own signature dishes. But come more customers ~ time is very difficult to ensure that the food is still as good as before; may be in the material, the cost of the use of alternatives. There are already a lot of restaurants with this problem, so strict control of food hygiene and quality is necessary.
Once again, the quality of the waiter; general restaurant waiters do not need a very high diploma, because the high diploma is certainly high cost. Secondary school or high school diploma can be completely competent waiter. But the company has to carry out a certain amount of training for the waiter, unified company clothing. I know how to deal with some difficult problems and polite language etiquette of the waiter.
Lastly, the speed of serving food; waiters must give customers the name of the dish when serving food, which is the most basic. The attitude must be good!
The above are not in any order of priority, they are all very important, I hope to be able to help you!
