Fellow food-lovers,
One of the reasons that I, as a vegan, have been pleasantly surprised by my recent visits, and have purposely and repeatedly chosen WDW as a vacation destination, is that they do (as an organization, anyway) take special needs of their diners seriously. I probably can't say it better than sixxmum and others have done, but the company wants to keep people on company property and they want to make sure that they accommodate special diets so that no one will have to go spend their money elsewhere. This may not be true at all restaurants nationwide or worldwide, but it is "company policy" at WDW to accommodate everyone. Many of the restaurants have begun printing on their menus that they will do their best to accommodate special dining requests and urge people to ask their servers to get the chef. Most restaurants stock rice and/or soy milk, gluten-free bread or cookies, and other options so that they are prepared for most possibilities.
The fact is, vegan meal prep isn't actually all that difficult. An adequate vegan meal, although a lackluster one, is pasta with marinara and salad, or plain rice and beans. That's typically what you see at most steakhouses as the solo veggie item on the menu. It takes very little imagination or effort. In fact, it's pretty easy to make vegan versions of most dishes (or other dishes that just happen to be vegan but are on the regular menu)--but sometimes a given restaurant will default to an unnecessary animal-based ingredient (e.g., butter in the couscous) which means that they have to do just a teensy bit more preparation to make it vegan/allergen-free/etcetera. With advance warning, this should be pretty simple.
I never go into a restaurant expecting a chef to prepare something special or unusual for me, but I do go in with the expectation that if I have let them know in advance about a special need, they will accommodate it, and that if they cannot accommodate it, they must let ME know in advance so that I can make alternate plans. At the very least, they need to be able to provide accurate information about ingredients so that I can make my own decisions. Any well-managed restaurant will have staff who are conversant about the ingredients and food prep methods because so many people have allergies and other dietary restrictions. In many restaurants, that is the chef or sous-chef. It doesn't take too much time to have a brief chat with the people you are feeding! Most have seemed genuinely happy to do so.
This side discussion is detracting from the fact that at most places on Disney-property, managed by Disney, they strive to be accommodating and want EVERYONE to have a "magical" time. Hence the pumpkin risottos and the coconut-crusted tofu and the noodle bowls and...well, I'm already getting hungry for my next trip!
