Thanks for ANOTHER great review and so quickly!!! Annette is right - this is a great day! :)
I actually enjoy the Plaza Restaurant quite a bit and consider it to be a hidden treasure. The prices are decent, the food (when we have visited) was very good (the Plaza Club stands out if you ask me, as does the chicken salad with fresh strawberries), the service was top notch, and the desserts (made in the Main Street ice cream parlor) were wonderful. A couple of years ago, in 2010, I was able to feed my family of five (including dessert) for $65, which is a steal, imho. For all these reasons, I regard the Plaza Restaurant as the best full service option in the Magic Kingdom. However, it has been three years since I visited, so things certainly could have dropped off a bit. I will definitely check it out again when I visited sometime in the next year or two.
Yes, we were on a dining plan for this trip. Desserts were included.
