What does he like to eat? By knowing that we could telll you if we had seen those things. I am super picky (so is DS8), too and we were able to find something at every meal to eat. I know at Ohana the eggs did not seem to have cheese in them. They had mickey waffles and bacon. They also have sausage and some potatoes.
We also ate at Garden Grill. He may not like the things served to adults, but it is served family style and you can get as much of whatever you want. For the kids it was baked chicken legs, mac and cheese that was orange, Stoffers I think??. For adults they had turkey with gravy, which I am sure you could get without and beef tenderloin, with a sauce or something that you could also get on the side.
I know at Chef Mickey's they had chicken fingers, pizza, the same mac and cheese as above and turkey and beef they would carve for you. They also have rolls and ice cream. I think rolls could be a meal themselves
Which meal is he less picky on? I know that sound strange but I know I am less picky on breakfast foods. They usually don't add sauces and marinades to those! Crystal Palace had a wide variety of breakfast foods to choose from. I think I ate the most when I ate there because I liked the most.
