Caseys at MK and also WPE at Downtown Disney (breakfast ONLY - no kids menu). However, on closer inspection you will see that the places that have no kids menu, generally don't have the greatest choices anyhow. Trica1972 has a list of the few of these locations in the sticky FAQ Dining Plan thread at the top of the Restaurants page.
Alternatively, if you went to a place like Sunshine seasons in Epcot you would find that you and the kids could all have the Asian stir fry - they do a kids portion there which is great.
