As a diehard Red Mango fan, I've missed my frozen yogurt fix during my time in Pittsburgh.
My visit to Sweet Berry only confirms, and in fact deepens, my love for Red Mango. SB is clearly an imitator of RM, Pinkberry, and other trendy tart-froyo shops. The basic idea is the same, but there's something lost in the execution. The end product is just as cool and refreshing, but the actual yogurt is thinner and less tart than what I'm used to.
It's still better than TCBY, but with Dave and Andy's just up the street, you can't help but wonder if you just might be better off choosing the real thing.
