In western food culture, the knife is only used to cut food, and it is impolite not to put food into your mouth. When eating western food, you must eat one piece of food and cut it, but not all of it. In addition, it is impolite to make a collision between the plates of the knife and fork box. Before going to a western restaurant, you need to pay attention to dress etiquette. Men must dress neatly, such as a suit. For ladies, evening dress is a better choice. It is best not to wear casual clothes to enter the western restaurant.
