    Eating in Western restaurant is a little different from eating in Chinese ones. It is to understand the differences and to act politely. As their saying goes, “When in Rome, do as the Romans do.”

    When you first arrive at the restaurant, you should wait for the waiter to you to a table. Sometimes it is all right to a table for yourself, but you should ask . In the Western restaurant, each person usually asks for their food or dishes and eats they ask for. Western people don't put all of the food in the middle of the table to share.

    One of the differences between Chinese restaurants and Western ones is that most Chinese restaurants are noisy, but most Western restaurants are and people there speak in a low voice. Don't shout to the waiters, people may think that you are rude.

    If you need help, you should try to ask with your eyes of your voice. It's better not to put up your hand, either.
