A restaurant , or an eatery, is a business that prepares and serves food and drinks to customers. Meals are generally served and eaten on the premises, but many restaurants also offer take-out and food delivery services.
Restaurants vary greatly in appearance and offerings, including a wide variety of cuisines and service models ranging from inexpensive fast food restaurants and cafeterias, to mid-priced family restaurants, to high-priced luxury establishments.
In Western countries, most mid- to high-range restaurants serve alcoholic beverages such as beer and wine. Some restaurants serve all the major meals, such as breakfast, lunch, and dinner (e.g., major fast food chains, diners, hotel restaurants, and airport restaurants).
Other restaurants may serve only a single meal (for example, a pancake house may only serve breakfast) or they may serve two meals (e.g., lunch and dinner).
Catering is the business of providing food service at a remote site or a site such as a hotel, hospital, pub, aircraft, cruise ship, park, filming site or studio, entertainment site, or event venue.
The earliest account of major services being catered in the United States is a 1778 ball in Philadelphia catered by Caesar Cranshell to celebrate the departure of British General William Howe. Catering business began to form around 1820, centering in Philadelphia.
Catering became a respectable and profitable business. The early catering industry was disproportionately founded by African-Americans.
