I posted about this very thing and from the responses I received, you can't get any snacks here except beverages as they don't sell popcorn, ice cream or fruit. I agree it's confusing and a big tease to go into a bakery and only be able to get a water, but most of the responses seemed to suggest that's the way it is.
For quick service you can check out All Ears for menus as they have croissant sandwiches and a few other things for quick service.
I agree that the Dining Brochure/list is a bit misleading - here's another one: they have milkshake, fries and burger on the quick service page but a few posters who love milkshakes say they have had no luck using credits for a milkshake for quick service.
