MK - Cosmic Ray's
AK - Flame Tree
DHS - Pizza Planet? (I'm not very fond of the counter service options there)
Epcot - The counter service in Morocco - I forget the name
MK: El Pirata y el Perico (I Wish)- otherwise Columbia Harbor House
Epcot: Sunshine Seasons
AK: Flametree
MGM: Starring Rolls (Yeah, why not? Muffins!!)
MK -- Cosmic Rays
Epcot -- Sunshine Seasons
AK -- Flame Tree Barbecue
HS -- None -- we go to a different resort each trip rather than eat at the Studios
I would pick Columbia Harbor House in MK over Cosmic Ray's if I was eating there. Cosmic Ray's has longer lines and is way more crowded in my experience.
mk: cosmic rays / pecos bills ,depends on which side of the park we are in at lunch
epcot : sunshine grill in the land great variety
studios : backlot express
ak : flame tree really good ribs for quick service and best seating by the little duck pond shady and cool.
