The staff at the restaurant collectively pooled $210 on tickets hoping they could take the prize.
And they thought they did - for about 20 minutes.
A friend of one of the workers texted him the numbers without realising the webpage was showing Wednesday's numbers rather than Saturday's.
The ticket had been a perfect match for the wrong day, bringing the celebrations to an abrupt halt.
"It was like getting punched in the stomach," bartender Charles Poveromo told The New York Post.
"There was just so much joy, and I can't put into words the feelings of euphoria that we all felt."
Poveromo's wife sensibly suggested he double check the numbers and the party came crashing down.
"It was like a balloon deflating," he said.
The dishwasher who had just quit reportedly picked his apron up and said "back to work."
