Update - October 28, 2015:
I have to undo this endorsement. I have stopped buying Nikkos because, in my experience, the quality is too inconsistent. It's rarely tasty and sweet; most often, it's sour-ish; and quite frequently, I'd say 5-10%, it has gone bad even before its consume-by date.
I have to say that Nikkos has definitely taught me to appreciate the tasty consistency of US brands. Fortunately, stores have been better stocked recently. I most prefer Fage and Oikos, followed by Stonyfield and Dannon. I have not yet seen Chobani here.
