My favorite treat on my last trip was the strawberry dacqueri at All Star Movies. Yumm!!
On my previous trip in 2000, we had some kind of shish-ka-bob (sp?) somewhere in AK that was some kind of peanut chicken. It was very delicious!! But I couldn't find it anywhere on our last trip. It was a walk up restaurant, with a very limited menu, no seating, similar to a turkey leg type stop. I have tried peanut chicken at other places (outside of WDW) and nothing has been even remotely similar to what we had.
On a side note...I had something called watermelon ribs at Hard Rock Cafe once, and they didn't have it the next time we were at a Hard Rock...those were wonderful also, and I've never seen anyplace with anything similar.
