There are plenty of unique restaurants in the complex, V & A, Spoodles, Flying Fish, Ohana, Crystal Palace- the list goes on. I agree with the idea that many of the people who go to Disney are not that adventerous and they want something comfortable and familiar and there is a place for that in the parks-and probably more than you realize. I do not see the Disney restaurants as over promising and under delivering. Aside from some of the selections in the food courts at the resorts, the food is very good. The beignets at POFQ are quite good (and yes, I have been to the real French Quarter). I work in the industry and am extremely impressed by the overall quality and execution of the food, we have never had a bad meal-by that I mean made wrong or it took to long, bad service.
I used to work for a major mid-western retailer (that recently changed ownership and will soon change names) that has breakfasts with Santa and the Easter Bunny in their restaurants every year, they charged something like $15.99 for kids & $17.99 for adults (I can't remeber exactly) for 2#20 scoops of boil in bag eggs, 3 links of heat and eat sausage, 2 slices of heat and eat french toast and a wedge of orange. That is overpriced and the quality was marginal at best. What did you get, to sit on Santa's lap for 30 sec.? The character breakfasts at Disney are so much better, it is not even worth comparing the two.
The food in the German Pavillion is almost as good as the Ox Yoke Inn in Ammana Iowa, The food at Alfredo's in Italy is as good as the restarants on Taylor Street in Chicago and you don't get 3 Mobil stars (Victoria and Alberts) by overchaging and underelvering. Now the prices are higher, but if you look at and tourist heavy destinations, the prices are almost always higher. I can guarentee you the prices at the McDonalds on Navy Pier Chicago are higher than the one down the street from home. Disney is np value, but it is no rip-off.
