New York City isn’t exactly lacking in legendary spots to grab a sensational sandwich, so it really says something that a pop-up by Michigan institution Zingerman’s Deli caused such buzz in the Big Apple. The legendary Ann Arbor. Michigan shop brought its award-winning sammies to NYC for the first time ever, hosting a one-day event at Chelsea’s Olly Olly Market on 7 October. New Yorkers flocked to get a taste of the Jewish deli’s famous Reuben sandwiches fresh off the line. Why so much buzz? These aren't just any old sammies.
