It's a fantastic concept of creating frozen yogurt that is naturally healthier for you! Unfortunately, like most sugar substitute or sugar free treats and sweets, the end result leaves you empty.
This was my lasting perception after trying Josie's in the District. Great selection of flavors, however, after multiple visits, I felt like each one was just off from my expectation.
The great service and good prices do redeem it and its convenience in the District saves it from a 1 or 2 star rating.
