Not quite the same thing as Plaza Inn's chicken, but during my July visit, the Chicken Karage sandwich (basically Japanese fried chicken) at Lucky Fortune was still just as good as it was two years ago, as was the Baymax Macaron.
Also ended up with a fried chicken sandwich for River Belle Terrace brunch that was decent, with a wonderful river view from the outside seats too.
Apart from those, the best thing I ate this trip was the seven grains gumbo with meat from Tiana's Palace.
Plaza Inn underwhelmed a bit this time around, honestly. At least my mother liked her pot roast, after otherwise feeling she had a relatively underwhelming experience with Disneyland food compared to what she remembered from a few years ago. I wouldn't quite go that far, but we did have a very disappointing run with snacks this time around.
I've never had cornish hen before, but I would absolutely order it if it wound up on a less exclusive DL menu.
