Epcot’s Sunshine Seasons on the first floor of the Land Pavillion is sort of cafeteria style, where you can pick and choose from a variety of offerings. We like it because it can satisfy, typically, the group since there’s the variety there. They can have some interesting choice there sometimes too. Sorry I don’t have a picture, but you can’t miss it.
However, as others have pointed out, you’ll be there during Flower and Garden Festival. There will be kiosks around the World Showcase area, and the food choices are pretty tasty. They are small bites, like tapas plates, so you can walk and eat, trying different items along the way. Check out this link for the kiosks and menus:

At AK, Flame Tree BBQ is really great, as others have mentioned.
At MK...hmm. That’ll be a little tough, because there’s a lot of standard fare offerings. Personally, I can just walk around with a big ol’ Turkey leg. Admittedly, once we had kids, I stopped doing that in favor of a more sit down place, which typically ends up being Pecos Bill or Cosmic Rays. I do think Be Our Guest can be a nice quick service, because it’s a little more than burgers/chicken sandwiches, but it’s difficult to get in (typically need an ADR for that one, even for lunch).
At HS, that’s another tough one but typically the Commissary. Not really exciting, honestly, but it’s indoors and we can sit down with the kids.
Enjoy!
