I would say any of the resort restaurants would be a little less crowded. If you get there when they open, you shouldn't have much of a wait. Anytime after that, you might have close to an hour wait at any of the places.
The park sit down restaurants will probably be packed and most likely not taking walk-up seating.
You might call and see what is available. People are calling in and cancelling some of their ADR's now.
