LOL...my DD7 said "Dad...Denny's is the best kid restaurant EVER! " because they have smiley pancake items and "rocket" cups! (Kids crack me up sometimes!).
We did delivery pizza on Friday night to Windsor Hills from Giordano's while the kids swam in the pool and the adults all had margarita happy hour! hehe Hit Epcot for our last night of fireworks and Illuminations!
There are literally 100s of restaurants nearby, it's Disney, most all of them are kid friendly.
Check here, I have a pretty extensive list of ones close by:
