Well since you will be in the DTD area, the POR has a nice food court as does the POFQ. The PORs food court is bigger. There is a big McDonalds in DTD.
Are you dead set on counter service? If you are visiting some of the other resorts, and maybe not looking for counter service, the Poly and the GF have nice sit down restaurants. The WL has Whispering Canyon which is pretty good too. Trails End in Fort Wilderness has a good breakfast buffet that is reasonable. You'd need to make a reservations at the sit down restaurants but you really have a pretty good selection
Here is a link to Deb Wills site you can take a look at what is available
