Now that Red Mango — the first big Korean fro-yo chain, and thus the progenitor of the new wave started by Pinkberry, which hails from LA — is coming to New York, it's time to take stock of the ever-growing number of frosty options. Since Pinkberry first opened its doors here last year, the dessert has descended across the city like a cold curtain. It was only in June that Rob and Robin shortlisted the new frozen-yogurt options, and since then /eks/ and, soon, Red Mango have been added. How to separate the Pinkberrys from the Yolato from the gelatos? We had to make up a chart to parse it all (full disclosure: We cheated a little by including Grom, which isn't strictly fro-yo — but it is an excellent new gelato spot). Below, our guide to the new yogurt culture. What’s your favorite? Email us and we'll print the results.
