I was looking forward to trying the chicken parm, until I saw the picture. Now that OP says the flavor is lacking too I will not order it.
Serves me right for thinking of bypassing my general restaurant rule, especially for new places: Order what they specialize in: pizza.
Sure, lots of WDW restaurants have fabulous dishes that are out of their speciality, for example the char broiled steak at Flying Fish. But it takes time after a place has opened their doors for the word to get out about different menu items. Sticking with the house specialty is usually the safe way to go for a new place.
