I don't think WDW is where I would choose to end my 10 year burger ban. Most of their burgers are average at best.
I would head for Five Guys or Red Robin.
If you are talking about a burger at WDW, stay away from the ones you get at any CS restaurant in the parks. I don't care how good the fixings bar is that some people will likely comment about - you have to start with a good burger.
Nobody mentioned the Plaza in the Magic Kingdom!![]()
We thought the best burgers were served at lunch at Le Cellier.
The ones at the Plaza are good because they are a bit cheaper, and they have several toppings that are included, if you want, such as cheese, bacon, etc.
