The tiny store sets up coffee urns in the morning. The only "grab and go" stuff I remember seeing would be pre-packaged muffins, danish, and bagels. By pre-packaged, I'm referring to single-serving items you'd find in a gas station or 7-11. I also remember seeing whole fruit like apples and bananas. They have cold drinks, so there's a possibility that the coolers would have some fresher items like fruit cups. I'm sure they'd have single-serve cream cheese.
I'd categorize it more as a place to grab something small to tide you over until you're in a theme park (or elsewhere) to get something freshly made.
