We're doing counter service dining plan for 10 days (also at Pop Century). One dinner out of pocket, Chef Mickey's.
I've had some concerns about "will we get sick of it?" but I think if you study menus prior to going, and have some REALLY good options (like Wolfgang Puck Express, Earl of Sandwich, etc) that it's doable. I know we'll do Cosmic Ray's for chicken and ribs, Flametree Barbeque for ribs, maybe do the Animal Kingdom "picnic" thing they have now.
Personally I could eat at Earl of Sandwich daily. It was THAT GOOD. Oh there is something at Epcot, in the Land, that has stuff like salmon or a grilled pork chop as a counter service. I think it's called Sunshine Seasons. Well I am babbling and not making my point....which is...that counter service can be somewhat diverse if you plan right.
