Queens is New York City's most international borough, so a ride on the 7 train—the purple-hued subway line that cuts through Long Island City, Sunnyside, Woodside, Jackson Heights, Elmhurst, Corona and Flushing—can feel like a journey around the globe. Indeed, in 1999, the route was named one of 16 "National Millennium Trails" representing the legacy of the United States, as it features an abundance of immigrant neighborhoods along its stops. Riding the 7 is certainly an essential NYC experience for anyone who's interested in world cultures. What should you do when you get off at each station? Well, eating is one great option. For guidance, check out our roundup of ethnic restaurants with tasty food along the diverse line. Conveniently, Flushing Meadows Corona Park is adjacent to Mets-Willets Point, the second-to-last 7 train stop. Also near the 7, you'll find innovative contemporary art at MoMA PS1 in Long Island City.
