In terms of food and theming, my favourites are Magellan's (DS), Ristorante Di Canaletto (DS), Vulcania (DS), Miguel's El Dorado Cantina(DS), Casbah Food Court (DS), Grandma Sara's (DL) and Hungry Bear (DL). Basically, I favour the restaurants at DS over DL.
If we were only including theming, then I'd add Queen of Hearts Banquet Hall (DL). The meals were okay, but nothing amazing.
There is also a new Junior Woodchucks Café (i.e. Huey, Dewey and Louie themed) opening at DL which I plan to try on my next visit. But, I have no idea what the food and theming will be like.
