The catering industry cannot write about catering services in general. It must be distinguished whether it is a formal meal service or a fast food service.

A restaurant or hotel is a full meal service, and a fast food chain or takeout service is a fast food service.

1. Dinner service usually refers to services that provide a more formal and high-end dining experience. Offering more varied and complex menu choices, focusing on taste, quality and creativity. Dinner service is usually provided in a restaurant or hotel, providing a comfortable dining environment, professional waiters and longer meal times.

2. Fast food service emphasizes speed, convenience and relatively low price. Fast food is served in fast food chains or takeout services, offering simple, standardized menu choices, often characterized by portability and quick service. Fast food is often an option for customers to get food quickly.
