1) catering comes from Cater, which is used to provide food for a group, an event or an activity; Usually, it also includes a series of supporting facilities such as setting up a stage, arranging and providing catering hooks. There are some catering service companies in Europe and America. They will deliberately arrange some special diets according to the needs of customers and the purpose of providing catering. For example, at the wedding reception, there are some light meals at the wedding site. These companies will make sandwiches, biscuits and western cakes, and provide carbonated drinks and champagne, and then there will be some special arrangements for the wedding. These may also include service providers and so on. So catering is a service.

2) The restaurant is just an ordinary restaurant, which provides meals and does not restrict anyone, events or activities. However, if a family decides to hold an evening birthday party in a certain area of a restaurant, especially for their children's birthdays, and invites other children to eat and play together, it will be included in the scope of catering. In other words, this restaurant not only provides food for ordinary customers, but also provides catering services, and then there will be some birthday party arrangements in this regard and so on. This kind of behavior is very popular in Europe and America, especially in fast food restaurants like McDonald's and KFC, where children like it.

Many times in China, we hold parties and order takeout. This is not a meal, but the food provided by the restaurant according to its own menu and then sent to a specific place.
