We've been to both. The food at Le Cellier is delicious and they do a fantastic steak!

If you have children though I would definately recommend The Garden Grill - the food was tasty and plentiful, and the character interaction with the children is the best that we have experienced. In fact we were so impressed with it that we wrote a piece for the Orlando guide:

I'm sure you'll enjoy whichever you choose to go to, but as the others have said make sure you make a priority reservation as they are both very popular.
