When we were there in june, a CS was a sandwich, drink and either an ice cream novelty, rice krispie treat or a bag of chips. I did find that it was more helpful to ask the cashiers than to ask the counter service help, (they weren't quite as knowledgeable). Also, you can use a snack credit to buy a whole box of donuts or an entire loaf of bread or a bag of bagels. They did have peanut butter, cream cheese and butter at their condiment counter, and no they would not take money for it.
