I ate all the sweet potato fries off of DS plate and they were amazing! We only had one child and they brought him a single plate of food (one chicken leg, fries, broccoli and mac and cheese. I am sure they would have brought more but he had been sick and only ate about two bites. They did bring my 19 year old a kids ice cream as he did not like the cobbler. We reordered adult food and got all we wanted. It's a very different character meal and while we did like it, I just don't know that it will ever be a repeat for us.
I would think they would have the option of food from the season's restaurant if they would be wiling to do that. They too however have a more "healthy" hint to the menu so not sure if that would work for your child. Doubt a hot dog or regular fries are possible.
