EPCOT
*Bratwurst with sauerkraut on a pretzel roll at Sommerfest in Germany
*Kaki-Age Udon with Shrimp tempura at Yakitori House in Japan
*Lamb Sharwarma plate at Tangeriene Cafe in Morocco and any of their baklava with a demitasse of their arabic espresso
*Quiche and a loaf of french bread at the Boulangerie Patisserie in France, and pastry, and another quiche... somebody stop me!
(I tried Sunshine Seasons Food Fair that everyone else raves about, got chinese food, and thought it was pretty gross -

)
ANIMAL KINGDOM
*Go try the new Yak & Yeti
*It's just McDonald's, but eating at Restaurantasaurus can be fun, stake out a table in the old Airstream trailer and oogle all the theming in the adjacent room!
STUDIOS
*Only decent counter stuff is at Starring Rolls
MAGIC KINGDOM
*Main St. Bakery - anything!
*Columbia Harbor House - anything!
*Cosmic Rays - BBQ ribs meal, rotisserie chicken meal, chicken caesar salad (best on property in my book)
*Eggroll cart in Adventureland now also has SAMOSAS!
*Dole whip float and pineapple spear at the Aloha Aisle in Adventureland
Also, if it's convenient, you can get very good sandwiches and pastries from the Boardwalk Bakery in front of the Boardwalk Inn in the Epcot resort area, and believe it or not the food court at the Pop Century gets pretty high reviews and has a few signature items like their daily "tv dinner" and tie-dye cheesecake.
And Disney Quest, everything there is great. Best burgers on property, rivaling Beaches & Cream and the Plaza, and excellent pizza (only good pizza in all of Disney World).
