To be fair, my family is spoiled when it comes to food. We have restaurants offering cuisine from all over the world, alongside local cafes that offer the very best of local farm-to-table foods, and because they're all right here competing with one another, you don't have to pay an arm and a leg to get an amazing meal.
While the US has food deserts, I think may of us could say the same. Outside of WDW, dining is/has changed, and WDW has not kept up. Where I live we also have many places that try to feature farm-to-table food, and/or local cuisine, and/or delicious international cuisine. While visiting WDW, we have taken to almost all quick serve and eating offsite.
On property, among the best food we've had was the food at the Epcot Art festival. I would love if Epcot added a year round place that served festival highlights. Mind, some of the booths serve similar foods year after year, that would need to be rotated if such a place was added.
A fun food from a few years back was Taiyaki. They are...more or less - Japanese ice cream sandwiches, but instead of being made with cookies or bread the outer sandwich layer is a fun waffle in the shape of a fish. (I think Sleepy Hollow long ago had a classic waffle topped with ice cream.) I have since found them at my local international grocery store, and the grocery store ones are amazingly really good! Somehow the waffle isn't soggy. To clarify though, these are not the kind of 'waffle' cone offered at places like Cold Stone.
This past year, the Epcot Art festival featured a dessert called deconstructed Key Lime Pie. I'm not a huge fan of the general 'deconstructed' trend, but this dessert was beautiful and delicious.
WDW used to be somewhat visionary and playful in their dining. One thing I'm hoping is that Universal takes the lead when they open their new park. Universal's food can be a bit hit or miss, but they have a huge opportunity to knock the socks off WDW. Universal could also stand to reform a few places.
