Stopped in Mesa, Arizona at the Boba Tea shop on the southwest corner of Dobson and Southern to introduce a friend to this Asian drink phenomenon. On the wall are layers of graffiti left by many, many a customer. For the uninitiated, boba tea is a cold drink, typically tea with a flavored syrup. The bottom of the cup is filled with small tapioca balls – you get a large-diameter straw to extract the boba (also known as bubbles) from your cup. We had green tea with green apple syrup – if you haven’t had boba, you just don’t know what you are missing.
