From the MK, the easiest would be Chef Mickey. You could walk there!
But by boat there is wilderness lodge Whispering canyon. Have to admit, last time we had the skillet we weren’t thrilled, but my DGD loved the place. That trip was about a yr or so ago.
By monorail, you have at the Grand Florian, 1900 park Fare, at Poly, Ohana.
HDDR is a boat ride and a 5 min walk away.
Those are the dinners with Entertainment (some sort of something to keep kids busy). The are just as many places just to eat food.
The only downside of eating at a resort is in order to get back to your own resort, you have to travel back to a park and then to your resort. Unless you were planning, leave the park, eat dinner and head back to the park.
Was there a reason you plan to eat your meals outside the parks?
