Too bad the part of American culture we seem to share the most is fast food. Really, it's not a very nice thing to do to the rest of the world!
Ain't that the sad truth....
Yeah, you aren't going to find truly authentic food in WS, some good stuff, yes. But not authentic. If you are in WS & hungry, I suggest you go over to the Swan & Dolphin to eat - you will get some great sushi (the resorts have a large Japanese clientele) and I think Il Mulino is fantastic, altho sadly I can't vouch for it being truly authentic as I have not been to Italy. But it is not American-Italian with red sauce & meatballs, kwim?
If you have been to France, or enjoy a good authentic French restaurant near you, I would skip Chefs in France. I trained in classical French cuisine. I made the mistake of eating there & expecting the food to be what I was used to.
As a general rule in WDW - the resorts are going to offer you better food than the theme parks. And within that, the few places that do NOT take DDP are going to be better.
