Beg and plead to see a list. They had one at the outside vendor when we were there Dec 2010 and I wish I had taken a picture of it. I remember it had normal sugar and nothing totally offensive (but still, it's chemicals) but I cannot remember if it had yellow. Yellow is one that doesn't seem to bug DS so we sometimes let him have it, so just b/c I let him have it doesn't mean it doesn't have yellow.
It really bugs me that this info isn't easily available. They should have it like they do at CS at Disney. Even though that binder gives me sad info sometimes (like gelatin in so many innocent cupcakes) it's great to have the knowledge.
