If they have everything on hand they should, but I just checked the menu and I don't see any white bread or even sliced bread of any kind except for maybe the kids turkey sandwich. So as long as its on a hamburger bun, a sub roll, a multi grain bun or focaccia will it still be OK?
I know people have posted is just bread, cheese and butter but if they don't serve white bread there is no reason to keep it on hand.
I'm in the same boat but my DS21, yes 21, will now at least eat hamburgers, but when eating out he will usually get a grilled cheese.
Every time we have been in WDW I have to check every menu to make sure if he will have anything to eat. We mostly do CS so its usually easy to find him something and only do TS for breakfast so as long as they have regular pancakes we are good. Oh if he doesn't eat, he doesn't eat, no big deal.
