I would never say that food in WDW is not great! From the counter-service restaurants to the Sit-Down restaurants, I can not remember one bad meal or snack or anything that did not taste good.
I have eaten a burger's, pizza, taco's nacho's, hot dog's, pretzels, prime rib, chicken, sandwiches. filet mignon, and much much more, like almost everyone who goes to wdw and I am always satisfied.
BUT(I'm sure everyone was waiting the for the BUT), I would say the price's are high, mostly because disney CAN make them higher then normal price's. I don't mind paying these higher prices because the food is alway's good.
Also it's not only disney who make the price's high, it is basically every amusement park in the US (Canada) because they know that they have you trapped.
I just got back from Hershey Park and I payed $9 for a Burger and Fry. So teh price wars are every where. But, was it good? YES
So either bite the bullet and buy food in WDW or make PB&J sandwiches. It's up to you
