I tried to pick places that had things other than just burgers and chicken fingers since we were there for a week
Epcot - Sunshine Seasons Food Fair in the Land -- great selection for everyone (and tons of desserts)
AK - Tusker House -- great chicken and wraps AND
MK - Columbia Harbor House -- good tuna sandwich and soup
Pecos Bill's -- great burgers and fixin's bar -- perfect spot for a quick dinner before Spectromagic
DTD - Earl of Sandwich
Our resort counter service also had a good variety (and if you're on the dining plan, they are very flexible with what you can get)
Have fun!
