I have now been to Cherry Berry four times and each time, I cannot change my flavor. I mix the Acia berry and pomegranete and put fresh strawberries, blueberries and the little fish egg things that are filled with juice.
I LOVE IT. If you sign up for the frequent visitor program (just give them your phone or email) and they'll keep a record of how many times you come in and you'll get 3 oz free every so many  visits!
