You list 10 trips. I just got back from my 22nd and I certainly haven't come close to trying all the restaurants on property so I'm sure there are some gems that you haven't experienced yet. It is kind of hard to give recommendations since we don't know where you've been, but I'll list some favorites outside of the parks.
Beaches and Cream, Whispering Canyon Cafe, Boma, Kona Cafe, Concourse Steakhouse, Narcooses, Wolfgang Puck Express.
If you will be venturing offsite, I'd highly recommend Sweet Tomatoes on I-Drive near Belz. Excellent selection, quality freshly made food and very reasonably priced. Another offsite favorite is Flippers pizza at Old Town. And Cafe D'Antonio in Celebration is wonderful for lunch or dinner.
