I suggest that you bypass both of these options and instead head for the Refreshment Port in Epcot. Not only can you get your fry-fix, but you can also order "chicken" nuggets, McFlurries (some sort of gelatinous frozen goo), and pretend coffee. The possibilities are positively dizzying! And ... there are nice shady areas for you and your family to cop a squat while you digest.
For atmosphere and variety, I give the Refreshment Port two Grimaces out of a possible three.
