The person I spoke with was very knowledgeable about cross contamination. Their only gluten free item is granola that is manufactured in a facility that uses wheat. They do have a gluten free granola option. Tell them you are celiac and they will change gloves, use a new cutting board, etc to prevent cross contamination.
Chain juice and açaí spot near the new Elk Grove Costco. Stopped for a berry bowl despite all the allergen warnings about possibility of wheat and gluten being present. Was assured by the employee who knew what gluten was and suggested their GF granola. Pretty delicious and no symptoms!
