A restaurant (from the French verb restaurant, meaning "to restore") prepares and serves food and drink to customers. Meals are generally served and eaten on premises, but many restaurants also offer take-out and food delivery services.

Restaurants came into existence throughout the medieval Islamic world. The Islamic world had restaurants where one could purchase all sorts of prepared dishes. Restaurants in medieval Islamic Spain served three-course meals, which was earlier introduced in the 9th century – an idea that meals should be served in three separate courses consisting of soup, the main course, and dessert.

Restaurants vary greatly in appearance and offerings, including a wide variety of cuisines, service models and extravagant menus … like “vinegar only” .
