Etymology

The word derives from the early 19th century, taken from the French word restaurer 'provide meat for', literally 'restore to a former state' and, being the present participle of the verb, the term restaurant may have been used in 1507 as a "restorative beverage ", and in correspondence in 1521 to mean 'that which restores the strength, a fortifying food or remedy'.
