We eat there once on every trip so it was last spring that we ate there. have it booked for our late April trip this year. We like it because of the menu. The food is good sit down food, not fancy by any means but definitely a great lunch spot for us. Something for everyone with the burgers, salads, philly cheese steak and the BBQ mac and the meatloaf. Boys love the loaded fries. Shakes are good as well, but I now just get a nice bottle of beer and then a tea to not stuff myself before heading back out for the fun. If you can get a ressie there, I would recommend it.
Coming from the northeast, food at the Plaza always reminds us of Friendly's, only pricier of course. It's a charming little lunch spot and a nice break from the park on a hot day. We've always had great service at the Plaza.
