I'm going around the same time and while we had pretty good luck at 60 days we're having a hard time moving anything around. In the EPCOT area, Ale & Compass (Yacht Club) is doing mobile order/takeout via the My Disney Experience app (it also has a walk-up lounge). At the Swan and Dolphin, Il Mulino, Kimono's, and the Cabana poolside restaurant are all doing mobile order/take-out via the Swan and Dolphin app. Big River Grille has recently reopened but it's my understanding it's not showing as available in the Disney app yet - but is on OpenTable (Il Mulino is on OT too - as are most if not all of the Swan/Dolphin restaurants). Martha's Vineyard Lounge (walk-up only) has started to serve the burger and a chicken sandwich from Beaches 'n Cream (but not the full B&C menu) - menu isn't updated on the WDW site. While it's a quick service, the food is fantastic at Primo Piatto (Riviera Resort) and only a skyliner ride away. Keep looking (I find searching for 4 vs. 3 to return more results but I have no scientific proof) and definitely consider the Touring Plans reservation finder as others have suggested. Good luck!!!
