HELL’S KITCHEN — What's wrong with salsa?

A man claiming he had a knife threatened to "kill everyone" inside a Mexican restaurant after the manager told him the eatery didn’t have any ketchup, the NYPD said.

The approximately 25-year-old suspect came into Tulcingo Del Valle at 665 10th Ave., between West 46th and West 47th streets, around 8 p.m. on Sept. 11 and asked for the condiment, police said.

When the manager told the man they didn’t have any ketchup, he became “irate” and told her he had a knife, the NYPD said .

“I’m going to kill everyone,” the suspect said, according to police.

The man, who never showed a knife, fled the store and headed north on 10th Avenue after the manager told him she was calling the police, the NYPD said.

Police searched the area but didn’t find him.

An employee working at the restaurant Tuesday confirmed the incident had happened but said he wasn’t there at the time.

The restaurant’s manager could not be reached for comment.
