One favorite. WOLFGANG PUCK EXPRESS. Its VERY VERY VERY good. Always consistent, always delicious. Never had an issue with the food there. Its so tasty and one of my favorite places to go.
Earl of Sandwich is decent, but its just a sandwich. A very overhyped sandwich. At the end of the day I have to decide whether I want a sandwich for dinner (EoS), or a bacon wrapped meatloaf with mashed potatoes (WGPE).....guess what? WGPE always wins every single time!
Not in Nov or Dec, when EoS has their Holiday Turkey/Dressing sandwiches.
I love WGP Express and will normally choose it over EoS, except for when EoS has the Holiday S/Ws. I could eat one of those every single day of the trip, for any meal.
As far as other counter service restaurants:
Epcot: Sunshine Seasons, Norwegian bakery, French bakery, Tangeriene Cafe
MK: Columbia Harbour House or Sleepy Hollow (sweet/spicy chicken waffle s/w)
AK: Flame Tree BBQ (unless my mom is with us--she has eaten there twice and got sick both times, so refuses to try it again) Also like a couple of sides at the Y&Y CS for a meal (chicken fried rice with egg rolls)
DS: nothing, but do like the cupcakes at Starring Rolls
DTD: Wolfgang Pucks Express, Earl of Sandwich, and Cookes of Dublin
Resorts: Pepper Market at CSR (love their huge chicken nachos)
