...where the word restaurant came from?
Like most things that have to do with formalized food, the word restaurant comes from French. It originally referred to boullion restaurant, a restorative broth that was served at taverns, inns, and roadhouses to revive weary travelers. As innkeepers began to offer more substantive meals than just broth, the name stuck and the broth name came to mean the place where it was served. Cool, huh?
Considering that restaurants used to be places you would go to be restored, to take care of your health, I can't help but laugh at "fast-food restaurants." Maybe if we keep in mind the origin of the word restaurant, we will be much healthier.
