My boys' faves have mostly been mentioned: CM (though the grown ups have found the food to be declining each time we return), CP, CR, RFC, H&V for breakfast, and Lilo and Stitch at 'Ohana.
They have never asked to return to Donald's nor LTT.
Garden Grill, however, is their all-time favorite place, by far. They also LOVE Biergarten and the dance floor with the oompah band.
