Romaine Reynolds, 30, came up from behind the 19-year-old victim and slashed him in the back of the neck with a fork inside of the tony riverside restaurant at 450 E. 29th St. at about 5 p.m. on Dec. 20, leaving him bleeding, police said.
Reynolds then advanced on the victim with a steak knife but did not injure him further, police said.
It wasn't immediately clear whether the two were employees of Riverpark, which offers main courses like a roasted chicken for $31 and a rack of lamb for $43, but police described the pair as "co-workers."
The restaurant declined to comment.
Reynolds was released without bail and ordered to stay away from the victim. He is due back in court on March 23, according to the Manhattan District Attorney's office. His attorney did not respond to a request for comment.
