No complaints here, kinda stuck to the drinks but that's what this business is about anyway. Why make it complicated?
Just tried an Apple n Greens smoothie, substituting fresh orange juice for apple juice in the recipe. Told the cashier I was "allergic to gluten" and she recommended this smoothie. There is a warning on the menu about allergies and all equipment is shared with wheat, dairy, etc. However, the blender pitchers are clean for each smoothie, so your risk is a clean (or not) blender pitcher if you're drinking all blended fruits and veggies. Finding the info on gluten free or not is not readily or clearly available, but it is there. It's on theirs paper menu, and online at the website. Do not recommend adding any powders or seeds, as I believe there is a higher risk for cross contamination and/or gluten in those ingredients. For celiac people like me, there is risk, as in all restaurants.
I'm obsessed with jamba. It's so healthy and delicious.
Many of their smoothies are gluten free!
