I have lots of recommendations for you as I love chicken and order it everywhere. My favorites are:
-Kona Cafe, coconut almond chicken (It is soooo yummy!)
-Wolfgang Puck Cafe, macadamia nut crusted chicken breast (My favorite!)
-Chefs de France, 1/2 chicken meal (so moist and flavorful)
-Tutto Italia, I have had both of these chicken dishes and they were both so good! Petto di Pollo - oven roasted chicken breast with tomatos and mozzarella, served with roasted potatoes (they substituted pasta for my potatoes)
Pollo Al Mattone - roasted-pressed chicken with lemon, herbs and hot red peppers
If you also like pasta I can recommend Wolfgang Puck Express in Downtown Disney. There is a chicken alfredo pasta that is delicious. Also, Mama Melrose has a chicken pasta dish.
Hope this helps. I have had more chicken dishes than this at Disney but these are the ones that stand out in my mind.
