Food operations can be classified by country, cuisine type, or specialty. Beverages include alcoholic drinks like wine, beer, spirits, and non-alcoholic drinks like water, juice, tea, and coffee. Restaurant types range from small bistros offering basic cooking to fine dining establishments with formal service and international restaurants serving different world cuisines. Cafeterias are primarily self-service while popular fast food and catering outlets meet demands for all-day dining and grab-and-go options.
