A thousand years ago the Chinese had an entirely codified kitchen while the French were still gnawing on bones. Chopsticks have been around since the fourth century B.C. Forks didn't show up in England until 1611, and even then they weren't meant for eating but just to hold the meat still while you hacked at it with your knife.
Every restaurant is a theater, and the truly great ones allow us to indulge in the fantasy that we are rich and powerful. When restaurants hold up their end of the bargain, they give us the illusion of being surrounded by servants intent on ensuring our happiness and offering extraordinary food. But even modest restaurants offer the opportunity to become someone else, at least for a little while. Restaurants free us from mundane reality; that is part of their charm. When you walk through the door, you are entering neutral territory where you are free to be whoever you choose for the duration of the meal.
