I had an English friend once comment that the "Tea" at GF was as much an English experience as the food at the American pavilion was fine dining and representative of the United States. Point taken.
There is nothing wrong with the offerings at Gf if they are to your liking, but do not go expecting a high quality experience or even one that is very authentic.
WDW is for fun, not so much for being genuine, eh? The magic encompasses the tromp l'oeil they pull off with almost everything they have to offer.
Same as 'Ohana. There isn't a thing Hawaiian or Polynesian about it. Do people love it? Of course they do. Do some dislike it? Yep.
That's the true magic of Disney. There really is something for everyone. If you don't like one thing, carry on. There will be something else that pleases you thoroughly.
