MK--Cosmic Ray's. And yes, I am just as surprised as you are. We had avoided this place because of the 'eh' reviews but decided to give it a go because of the rotisserie chicken option for our DS, who has to eat gluten-free. The chicken and the green beans were really good and it is a nice to have a change from the same ole burger and fries.
Flame Tree--The BBQ is good and the setting is lovely.
Epcot--Tangierine Cafe. Theirs is the food I crave when I'm not at WDW, not something from a TS restaurant. That shawarma platter is deeee-licous.
DHS--Backlot is the best of the 'eh'. The grilled turkey and cheese is pretty good, and so is the avocado burger (sorry, I know you were asking about things other than burgers, but at least it has avocado on it!) We've tried the Commissary (yuck) and Pizza Planet (okay.)
