LeCellier has a great burger.
Without a doubt, Beaches and Cream.
It is really good though!! Also agree Le Cellier's burger is very good. The Plaza has decent bacon cheese burgers, not great, but better than the CS burgers and a good lunch option when in MK.Without a doubt, Beaches and Cream.
Thus far, the Grand Floridian Burger is the best I've had on Disney property. It is indeed $18, but it's well worth it in my opinion.
