I would do a french lunch, the quiche/onion soup makes a great lunch/brunch (it may be on the special too, don't remember).
I have had the filet at both LeCellier and LeChef's and I really did not care for the french one as much and 2 days in a row would be alot for me.
Never eaten at Coral Reef. Main reason being that it is all the way at the entrance and not in World Showcase.
