Agreed with others!
AK- FLAMETREE! Definetly best qs food and you get a lot! Check out the menu!
DTD- Wolfgang Puck Express. Last trip I went on was with all 20 yr. old boys, and they were even completly FULL after eating there. We did leave a small tip though, because they do have people coming around cleaning and asking if you need refills.
MK- Either Pecos Bill or Cosmic Rays, Cosmic Rays has some actual meals at it, and both have toppings bars so you can add as much stuff to your burgers, nachos, etc.
Epcot- Sunshine Seasons, has tons of variety and again nice portions! They even have a great selection of dessert to choose from. Our other little favorite spot is Tangierne Cafe in Morrocco. If you're up for trying new things this meal include chicken/lamb, hummus, cous cous, pita bread, some little yummy salad that I can't remember the name of...check the menu ! But it's all reallly good and you will feel very full after!
DHS- as far as I'm concerned..it doesn't seem like there's much there...so we never ate there!
HAVE FUN!!
