We haven't tried Coral Reef yet, but eventually will. As another poster said, the CM's at LeCellier are the best!
That being said, we've now visited Le Cellier three times since moving here in July. My younger son (5) even asked to eat there when we were in Epcot two weeks ago. He's my daring boy, will try anything (but vegetables) once. But even my 8 year old, who's got lots of food issues, will gladly eat at Le Cellier.
And they don't even know about the chocolatte mousse! The breadsticks and soup are guaranteed to be ordered with everything else.
Went with 3 coworkers in November for lunch. Hands down, that was the best burger I have ever eaten.
So for an unbiased opinion (not!), eat at Le Cellier.
