Our plane pretty much always arrives late and we are always starving when we land so we have much experience with this. Though the
CS at GF and Poly are technically open 24 hours, after 11 p.m. there is no hot food. Only refrigerated and snack type stuff. We've done Picabu at 11ish - highly recommend - and the grill was still working but I am not sure if it operates 24 hours.
The McDonald's by All Stars is open 24 hours (the drive thru, at least. Lobby is open until 1:00 a.m.)
Nothing at DTD has ever panned out for us late night.
I would consider off-property. Last trip, we went to the 24 hour Steak and Shake just off property. We don't have them in Colorado so it was something different for us!
Giordano's, a delish stuffed Chicago-style pizza chain, is near Steak and Shake and is open until at least 11 - we planned to order a pizza when we got our car at the airport and pick it up on our way to the hotel but we had a luggage snafu so couldn't do it this trip.
Maybe some of this is helpful?
