Everyone has their own opinions in which none are wrong or right, and I of course respect everyone's opinions. Nothing at Disney would I ever classify as "the best [insert food type here] I have ever had". That title is reserved for French Laundry in Yountville, CA. (Napa Valley) By far the best meal I ever had to this day.
The best pizza & Italian food in general I have ever had was in Sciacca, Sicily, Italy and nothing I have ever eaten after that has been anywhere close. The best seafood I have ever had was in the panhandle area of Florida on the Gulf Coast. The best Korean food I ever had was in Inch 'on South Korea. etc., etc., etc. Where certain restaurants are a great representation of [insert style of food here] cooking, nothing compares to having it at the "source", as it were.
I dated a girl in college who lived in Narraganset Beach, RI. and dined at Flatbread Pizza Company in Providence on many occasions. It was fine & better than a lot of places, though (my opinion) nothing special. I do miss Mediterrano's in Providence though
Food/restaurants in Boston, New York, Las Vegas, etc. are no better or worse than any other major city in the US I have lived in or visited. All very good and differ from each other which makes for unique and different dinning experiences.
To me, the best meal I have eaten on Disney property was at Flying Fish (about three weeks ago). We have dined at Victoria & Albert's many times, including the Chef's table several times, and where it was a very good meal ... I have had better at other restaurants for similar or lesser price.
I'm not sure why people have labeled or expect Disney World to be some 'foodies' destination for great food. Where some locations here are very good. I wouldn't consider it a destination for "great" food by any stretch. We enjoy many locations here on property, though we know what to expect, what to order, what days to visit, etc. All that honestly plays into the experience you have at dining locations at Disney.
