The business has been closed this past week... and there isn't any notice on the premises to patrons at the well-regarded restaurant (try the Big Plate Chicken) about what's happening here.
However, there is a post, dated July 18, on Instagram: "Jiang Diner has been in constant operation throughout this pandemic ... It is time for us to take a break. We will be back."
Jiang Diner debuted in the spring of 2019 "with a mission to introduce authentic Xinjiang-styled Northwestern Chinese food and culture to New York City."
You can follow them on Instagram for reopening info.
