I started answering this ... and then I realized who the OP is
We love Pecos Bills & Columbia Harbor House at the MK and the fish & chips in England at Epcot. Another favorite for DH, DS, and DD (but not for me

) is the cantina in Mexico. We've never found a place we love at the Studios, and for some reason we always end up snacking at the Animal Kingdom. I'm not sure we've ever had a counter service meal there.
