Please clarify. Do you want to find a place to dine DURING these shows (by the way, Wishes is not a parade) because it's easier to get an ADR when everyone else is outside watching the parade/fireworks?
Or do you want to find a place to dine AND watch these at the same time? If this is the case, then you'll be out of luck in the MK. There is no restaurant with views out the windows for the parade or Wishes.
The only place where this is possible for Illuminations is the patio at Rose and Crown (but you can't be guaranteed a patio table), or a window table at La Hacienda (again, this can't be guaranteed and they don't take requests). Some have reported a partial, obstructed view at Tokyo Dining and Les Chefs de France from a couple of window tables.
Honestly your best option is to eat before or after these shows and to stake out a place in the open air to watch them.
