MK- Pecos Bill's, Columbia Harbour House, or Cosmic Rays (also love the Spicy cheese pretzels at the Lunching Pad & Dole Whips!)
Epcot- We haven't eaten many CS meals here, so not sure
HS- I guess Pizza Planet (it's alright)
AK- used to be Tusker House before it became TS, so I guess Flame Tree BBQ
DTD- Earl of Sandwich
We tend to eat a lot of our CS meals at the resort, so sorry I don't have too much to compare to...
