I saw on another site a discussion about a free hazelnut or caramel machiatto at starbucks. There is supposedly a flyer in some stores but people are being successful even in other stores by giving the barista code 350.
My focus is on the kashrus of these drinks. According to my quick research the caramel machiatto is not kosher but I cannot find any info on the hazelnut, which apparently is a new drink. Anyone know anything about this?
