Where we've featured it
Sunrise Mart is indeed actually a mart - a little Japanese supermarket to be specific, with a few locations throughout the city. The rice bowls make for a decent lunch, but you're really coming for the extensive collection of Japanese snacks. Bring some green tea Kit Kats back to the office and wind up a hero.
Before H Mart came to the East Village, there was Sunrise Mart - a Japanese grocery store on Stuyvesant Street where you could get cookies from Hokkaido, uni, matcha powder, and superior Kit Kats. Now Sunrise Mart has locations all around NYC, including Soho, the East Village, Midtown, and (most recently) a big food hall set-up in Industry City. The Industry City location has its very own tofu counter, as well as a wagyu beef station and tons of fresh fish. Also, the Midtown Sunrise Mart sells a bunch of health and beauty products, which make for excellent gifts.
