Definately don't want to eat alot of burgers/ fries/ chicken strips on a QS meal plan
Alot of ppl do and It gets old really fast LOL.
There are lots of great QS places with variety.
Just takes a little research. Here are some that come to my mind in parks and resorts:
In Magic Kingdom: Totally agree with BOG breakfast
and lunch in MK can't go wrong there.
In Animal Kingdom: Flame Tree Barbecue ..
St. Louis Rib Dinner or Rib and Chicken Combo
Don't forget you can also try out
Satu'li Canteen - in Pandora.
In Epcot many cuisines to try
France:
Boulangerie Patisserie les Halles (they open when the park opens so you can get QS breakfast there!)
In Japan: Katsura Grill
In Mexico: La Cantina de San Angel
In Morocco:
Tangierine Cafe
In England: Yorkshire County Fish shoppe
In Hollywood Studios ABC Commissary for Dinner:
Lemon Pepper Salmon or Chimichurri Steak are good uses of QS credit
At Resorts:
Animal Kingdom Lodge - The Mara
Contemporary - Contempo Cafe has some great entrees for dinner! Definately a great choice.
At Fort Wilderness - P & J's southern takeout (right by Pioneer hall and Trail's end restaurant)
You can get the fried chicken that they serve at the Hoop Dee doo show, plus some other great entree choices.
Polynesian: Capt Cooks - for breakfast you can get Tonga Toast (same as they serve upstairs at TS Kona Cafe)
Hope this helps get you started.
