As avid global travelers, one thing we really didn't want to do when we started having kids was have every holiday at Disney. Bricklet gets one holiday a year targeted at him, tops, the rest needs to have things for us. That said, a couple of months ago I did attend a conference in Orlando and J and Bricklet came to meet me there and we made a long weekend of it. I was a bad blogger and didn't photograph any of my food - but did learn exactly how hyper-friendly Disney is for food allergies.
I stayed at the HIlton Buena Vista, which was really GF friendly. I ate in all restuarants and each accomodated me. They had good quick grab items (like Kind Bars) in the deli. I was so really excited as this was the first conference I've been to where they had GF meals ready upon request (sandwiches, with bread that was actually good).
We only went to the Magic Kingdom one day since Bricklet was still quite small and we have extended family in Florida, so we only had to sort out two meals. We ended up at Tortuga Tavern for lunch (it was meh), and Cosmic Ray's Starlight Cafe for a late lunch (also meh). While the food was really mediocre, the service was good everywhere we went. Oh, and I may have had more than one chocolate covered banana. Those things were totally as good as I remembered!
Downtown Disney has the only place I've been to with gluten free onion rings - Raglan Road. The place is horrendous in that Disney over the top tourist trap type way, but the food is very good (and GF onion rings FTW!). I went twice. My best suggestion is, especially over a weekend ensure you reserve (and reserve far ahead, the week prior didn't do me any good, so we only managed to get tables during the week) .
T-Rex was the funnest place we went. Bricklet loved the animatronic dinosaurs - and it aligned with our goal of making him obsessed with dinosaurs (because they're awesome). We managed to get a day before late lunch reservation. The queue that you wait in when you have a reservation was quite shocking... but Downtown Disney + weekend = it is what it is.
Out of Downtown Disney and the hotel we went to Ruth's Chris for steak (filet was great), Sea Dog Brewing (yum, burgers).
My only disappointment was Erin McKenna's (Babycakes) was listed as still being in Downtown Disney, but it had closed / moved.
