You don't have to be concierge to get these items. Anyone can order them (even if you're not a guest at the GF). You must have them delivered to a restaurant at the GF (1900 Park Fare, Citricos, etc) or the afternoon tea. If you are a guest at the GF (concierge or not) you can have them delivered to your room. I've even read of people ordering them from the bakery and picking them up at the GF and taking them to another resort.
HTH!
