Unusual Restaurants In The World

A restaurant owner is called a restaurateur ( /ˌrɛstərəˈtɜr/); both words derive from the French verb restaurer, meaning "to restore". Professional artisans of cooking are called chefs, while preparation staff and line cooks prepare food items in a more systematic and less artistic fashion.
History
In Ancient Rome, thermopolia (singular thermopolium) were small restaurant-bars which offered food and drinks to the customer. A typical thermopolium had L-shaped counters into which large storage vessels were sunk, which would contain either hot or cold food. They are linked to the absence of kitchens in many dwellings and the ease with which people could purchase prepared foods. Besides, eating out was also considered an important aspect of socialising.
