For sure I think you should check out the Board Walk.
Captain Cook's in the Poly. Not a food court but the QS option there. Some yummy flatbreads, different selections such as the aloha sandwich, adult grilled cheese, and chicken lo mein. The best parts? The Polynesian chips and the self-serve Dole whip station!!
I also second the Riverside Mill. The build your own salad and pasta stations were wonderful options. My DH really enjoyed the build your own sundae bar as well.
