Doesn't this seem obvious? I'm not being smart when i say that, I'm agreeing with what you say, it just seems THAT obvious. I mean, I think this should hold for ANY restaurant.....Burger King, Subway, etc. Our expectations at ANY place is the same, and it has translated into extremely well behaved kids in restaurants, and yes, even our 2 year old who will be 3 this fall for our trip.
It helps that our older kids model great behavior, AND at the very first , slightest hint of an issue, we take care of it. This may be pulling out something to do, taking a walk to the bathroom until the food comes, or at the very worst case, removal of the child from the restaurant. This of course means one adult doesn't eat. In all our years, and 4 kids, we had to do this ONCE. Our oldest daughter was 2, and it was a Big Boy in northern Michigan.
Regardless of what some snobby posters on here may think, kids are very capable of behaving and eating in places like this. For the non-kid crowd at Disney,

there is Victoria and Alberts, and also the upstairs french place in Epcot, right?
Finally, I can't emphasize enough about getting ALL the kids a nap. PLUS, another tip....DRESS UP!!!! I think this puts everyone in the frame of mind that something special is happening.
That's all.............
