Gotta disagree here. Three different issues in our family, all handled wonderfully by 95% of restaurants we visit. Food allergies - have talked to servers at more restaurants than I can count, explain the issues, ask questions, maybe request an "off menu" something - have never been turned down. This is actually something Disney has done pretty well (for example, asked at San Angel for a salad with just chicken and certain vegetables. Best salad ever; don't even remember the price) - but certainly pretty much everyone does it.
Issue with needing food for a different type dietary restriction - typically subbing grilled for breaded or fried; and different side choices. Again, never denied, from chains mentioned and local places. Have also needed smaller portions for a post surgical person - even have a little card to show - again, never turned down; virtually all positive experiences outside of Disney.
I've never considered these "entitlements" - I can vote with my feet and my dollars and not return to places that can't make simple adjustments. That's the point of this discussion IMO - yes, Disney COULD make reasonable accomodations/adjustments for many of the issues discussed here. They have/may choose NOT to; so we are discussing our opinions and options. For our family, that will likely mean much more quick service or bringing food with us - both scenarios lose Disney money. Or Disney could listen to their loyal clients, and make adjustments that ARE industry standard (see all the restaurants with "Senior Sized" or "Light" menu options) - the current scenario doesn't seem to be solving the problem, and seems petty and very much in line with the company's "charge more for less" standard these days.
