Our favorites:
Animal Kingdom: Hands down, Flame Tree BBQ
Magic Kingdom: Village Haus in Fantsyland, Cosmic Ray's in Tommorowland, El Pirata y el Perico if it's open (seasonal) in Adventureland; Pecos Bill in Frontierland;
Hollywood Studios....This park doesn't have much that is outstanding....burgers and pizza everywhere, occasionally something different but not great. ABC Commissary has an Asian salad that is decent...their fish is hit and miss either it's good or it's greasy, so I try to stand aside and watch for someone to walk by with it...if you can SEE the grease as they walk by, don't get it, lol. Studio Catering Company has probably the only menu with some flare...the pulled pork is good, but not as good as Flame Tree in AK; the chicken is ok but at least it's not a burger or pizza! This is probably the one park that I work hard to get TS for lunch and dinner....50's and Sci Fi are our favs. It's also an easy boat ride to Swan/Dolphin where there are some other great TS meals available, if you're willing to leave the park.
Epcot: This park just oozes with great food.....if you want a burger like every other park has then go to Electric Umbrella in Future World....otherwise, eat your way around the World in World Showcase. Some favorites:
Canada doesn't have a CS that I know of....unless you count the McDonald's that is just before it, but I hope not!
United Kingdom: Yorkshire Fish and Chips....this is the same recipe that you pay double plus for inside Rose & Crown. Yummy! Eat it overlooking the lagoon for a peaceful meal.
France: Boulangerie Patisserie....I know most people go here only for the sweet treats (and they are definitely fabulous), but the croissant sandwiches are wonderfully fresh and delicious. If you can resist the sweets in Boulangerie Patisserie, then go outside to the crepes kiosk for dessert.
Morroco: Tangierine Cafe, love the Shwarma Platters and they're typically enough for two light meals. Coucous is a great mini-meal.
Japan....Yakitori house had many great choices, not a bad one in the bunch!
America: Sadly just burgers, hot dogs and chicken strips. Since I get these in "real" life way too often, not my choice when there are other countries to explore.
Germany: Brautwurst and sauerkraut at the Sommerfest CS is pretty good...and the apple strudel is good too.
China: Lotus Blossom is the only CS choice for lunch (though the tea stand is an excelent beverage choice). Lotus Blossom is typical Americanized Chinese food, ok tasting, but sadly not really representative of truly great Chinese food. The pot stickers were much better than the egg roll.
Norway: Kringla Bakeri has some really good soup and sandwich combos, I think one comes with the famed rice cream, but I like the Schoolbread better as my dessert.
Mexico: The combo is definitely more than enough for two. This wasn't that great of food, but it was edible and filling, just nothing to write home about. The churros are messy but delicious. I'm not a drinker, but those in the know love the Margaritas.
