We ate here in September 2012 on the dining plan. It was a decent experience. I would highly recommend to save a TS meal for almost any other restaurant I've dined at at WDW. You can get most of the entree items offered at The Plaza at quick service locations throughout the resort. The only thing that set this dining experience apart was the dessert. I'd recommend to get dessert for a snack at The Plaza Ice Cream Parlor next door and save the TS credit/money for other things.
This place is great.. I have eaten there a couple times now and have a reservation for this weekend.For table service the price is great as well. My wife and son and I all can get out of there under $40.. normal Quick Service places cost us around $35. I think it might be the best value in MK for a meal.
When visiting Disney, we usually eat here on our last day at lunch time before we leave for the airport. The place is small and the wait can be longer than ideal without a reservation at dinner time, but the food and service is excellent - nothing fancy, but definitely good quality. We've also found that we can eat lunch there for the same price we would pay at many counter service locations.
I recently had dinner at the Plaza Restaurant for the first time. Its a very small place serving mostly sandwiches, shakes, and ice cream. I had the cheesesteak sandwich, it was fine for what it was. It was simple and tasty but maybe a bit too much bread and not enough meat. I try to eat clean and healthy most of the time but I have to say that the best part of the whole meal was the french fries! They weren't the typical Disney french fry that you get everywhere from counter service to table service. They were perfectly golden and crispy steak fries! More than likely they still came out of the freezer just like their counter service counter parts but they were so full of potato flavor, soft on the inside and crispy on the outside. So for me the sandwich wasn't all that memorable but the fries were fantastic, I'd go back in just to have those fries. So if you're looking for a simple, unfancy sandwich joint in the MK the plaza is the place for you. Its better than Magic Kingdom counter service but there is definitely better food elsewhere on property in the same kind of price range.
Plaza Restaurant is a table service restaurant located along Main Street USA in the Magic Kingdom.
