In the western food culture, the table knife is only used to cut the food, you can't bring the food into your mouth, this behavior is impolite. When eating western food, the food must be eaten piece by piece cut piece, rather than all cut together. In addition to this, there should be no clashing sound between the knife and fork box plate, which is also impolite behavior. You also need to pay attention to dress etiquette before going to a western restaurant. Men must be neatly dressed, such as a suit is a better choice; women, evening dress is a better choice. It is best not to wear casual clothes into the Western restaurant.
