By far one the last options IMO. Epcot has a literal ton of food options.
1) You could look at places at BW/BC/Swan/Dolphin for sitdowns if you really want that (even places like Sebastian's at CBR is easy to get to)
2) A variety of options for you that are good:
- Boardwalk Bakery - Boardwalk
- Primo Piatto - Riviera
- La Cantina - Mexico
- Regal Eagle - US (best BBQ on property now)
- Sommerfest - Germany
- Yorkshire Fish Cart - UK
All of these places will be great meals and for us Regal and Primo are MUST STOPS during the trip. Big benefit of Primo is you can mobile order and there is lots of places to take your food to eat if the weather is nice.
Festival switches out the week of Thanksgiving so M-TH there is no booths that week and the first weekend you can assume it will be much busier with locals/vloggers coming for the new booths.
