Ones that I have never eaten at and totally do NOT have any intention of eating at:

Victoria and Alberts
Flying Fish
ESPN Club
Fulton's Crabhouse
Ones that I have never eaten at, don't necessarily care to eat at, but don't completely rule it out either:
Marakesh
Rose and Crown
Shutters*
The Wave
Polynesian Lua*
Ohana*
Rainforest Cafe
The other Restaraunts at Downtown Disney, excluding the ones I already mentioned above, and T-Rex, which I have eaten at
*Whenever we stay at a resort, I want to experience a/the full service restaraunt of that resort, so if we ever stay at Carribbean Beach, Shutters will be a must. If not, then I could take it or leave it. Same with the restaraunts at the Polynesian. While I'm leary of trying Polynesian cuisine, I may get bold and try it on a future trip, or if we ever stay at the Poly, it will be a must.
Between all the above restaraunts and all the ones we HAVE eaten at, that should be almost all of them. It's probably that I overlooked several though, such as any at the standalone DVC resorts, and I don't know the names of all the ones at DTD. And I didn't count any of the restaraunts in the Swan or Dolphin, since I don't consider those to be real Disney resorts and therefore, their restaraunts don't count.
