We came across yogurberry frozen yogurt in Buckhead and I highly recommend checking them out! Brian who is the general manager is awesome and even though it was freezing outside, the frozen yogurt was delicious! Here is the combo we settled on:
half lychee half taro with reese's peanut butter cup, heath bar and hershey's syrup. . . wow!
Run, don't walk to yougurberry in Buckhead. 3280 Peachtree Rd. Ste. 140B (and they validate!!)
