We did just that on Aug 26, LeCellier for lunch and CR for dinner.
We were on the dinning plan as well. I had the mushroom fillet
at LeCellier and it was truly delicious. The chocolate moose
was good. I had the salmon at the CR and it was ok. The
chocolate wave though was outstanding.
My two boys had the NY strip at both places and they gave
the edge to CR. I think they like the ones at CR because the
cut was bigger

. Wife had the Mahi Mahi at CR and thought it was
great. She had the Halibut at LeCellier and thought it was a bit
overcooked.
I would do both again. The portion is just right for me so I
don't think you will be overwhelmed with being too full.
We had lunch at LeCellier at 12:15 and dinner at CR at 8:10.
I didn't need any snack in between.
My boys did ask for extra bread sticks at LeCellier. They were
delicious.
