Everyone has suggested the same two I was going to - for lunch hours either The Plaza - convenient location as you enter MK, good prices, quick food but quailty table service. LTT has great lunch food although no characters at lunch, and deeper in to the park. LTT character dinner starts at 4pm - sounds like that may work for you to make an ADR right when they open. This was our favorite character meal in all of WDW. My kids ask to go to this one every time. Not gourmet food but traditional family style Thanksgiving fare, which my kids ate almost every bite of.
