Jackson Hole, a popular New York City burger chain, has abruptly closed its Upper West Side location, West Side Rag reported.
The online newspaper said that the location at West 85th Street and Columbus Avenue posted a sign Thursday morning announcing the closure.
"It is with great regret that we have decided to close our doors after 42 years in business," the restaurant said. "Thank you for all your support and great memories."
Some people passing by the restaurant, which had also papered its windows over, gasped as they walked by, according to West Side Rag.
The restaurant, which serves dozens of varieties of burgers and dozens of other menu items, still has four other locations in New York City and another in Englewood, New Jersey.
NBC 4 New York has reached out to the restaurant seeking comment.
