I could get a box of frozen strawberry juice bars at my grocery store, but they taste so much better when they come out of one of those little carts in the parks!
Fortunately for fans of the stuff, that isn't true. You can even buy the mix!
Personally, I think it's bland. My fave treat is the , followed by schoolbread. There really isn't anything I only eat in WDW that's available everywhere.
This might sound crazy, but my DBF and I could get McDonald's french fries anywhere, but we only ever get them at WDW. We're not breakfast people so they always end up being our late morning snack before lunch. We don't eat much fast food when we're home and seriously, I think the fries just taste SO much better at WDW. Always hot and crispy - it probably helps that it's the only item being prepared at the fry carts...
