|Much or all of what Jamba Juice offers seems to be gluten free, but the person taking our order didn\'t seem particularly knowledgeable about gluten. However, he did offer to show us the ingredient list for the beverage we wanted to order, the Orange Dream Machine, which is a heavenly blend of orange sherbet, frozen yogurt, and orange juice. It appeared to be gluten free, and we ordered it without a "boost" (vitamins, protein, etc.) since we didn\'t know definitively if those were gluten free. They\'d be smart to post a "GF" notation next to the gluten free items on their menu -- or include this information on their website.
