Try Mama Melrose at DHS. Pretty good chix parm, went there last April and had it.
Mama Melrose is a good suggestion. You might also try Via Napoli at Epcot. Tutto Italia's chicken parm is more authentic and less American-style.
It's threads like this that prove my point about not completely trusting what others say about various WDW restaurants. Some may love a spot, while others hate it. All you can do is give it a shot yourself and see what you think. It's only one meal....not that much to lose.
There truly is something for everyone there.
