We also liked Columbia Harbor House in the MK. We got a combination of fish and chicken strips and fries, dessert, and a drink, all included on the dining plan. And it was all yummy.
We ate at Pizzafari at AK and thought it was good, but I can't compare because we haven't ate anywhere else. We really liked it, but I was craving pizza and knew they had a lot of indoor seating, so that made our decision pretty easy!
