The structure of the catering industry includes both commercial and non-commercial establishments. Commercial establishments include five-star hotels with restaurants and coffee shops, medium hotels similar to five-stars but less luxurious, and free-standing high-class restaurants. Non-commercial establishments include snacks bars, fast food centers, night clubs, industrial canteens operated in factories on tight budgets, institutional catering in hospitals and colleges, outdoor catering providing services off-site, and disaster catering providing food during emergencies. The catering industry caters to customers across different price points and service levels.
