This wasn’t the slice he was hoping for.

A Bronx man trying to enjoy lunch at his favorite pizza joint had his face slashed and his eye socket broken with what he described as “a Mike Tyson punch” in an unprovoked bias attack, the victim told The Post.

Chris Bilcik, 59, said he was sitting alone in Ray’s Pizza on East 138th Street on Oct. 6 when the unhinged man walked in, grabbed a slice of his own, and launched into a racially charged diatribe for no apparent reason.

“He starts rambling about ‘f–king white people,’ then he turns around and starts gesturing towards me about the evils of the white man, talking about how they’re the devils of the world,” said Bilcik, who is white. “And he’s pointing at me.”

The assailant, who is black, then tried to sit down at Bilcik’s table, despite the Mott Haven slice-shop being practically empty.

“You’re not a white man, you’re a white boy,” the suspect allegedly sneered, but rather than escalate the confrontation, Bilcik just got up and moved to another table, he said.

But the run-in wasn’t over.

When Bilcik got up to throw out his trash and leave, the guy was waiting by the door.

“Stupidly, I just hoped he wouldn’t do anything,” said Bilcik, a registered nurse and aspiring writer who’s lived in the neighborhood for nearly 20 years.

When Bilcik tried to maneuver around the thug to the door, he smacked Bilcik in the face.

“I threw coffee at him, and then he punched me,” recalled Bilcik. “It’s a Mike Tyson punch. I’m lucky he didn’t keep hitting me.”

The brute also cut Bilcik across the face with a sharp object during the scrum, captured in brutal detail on surveillance video posted to YouTube by Bilcik.

“When I got hit, I felt very dizzy. My eye was mostly closed, and I had severe double vision,” he said. “I could’ve been knocked out. Blood was gushing from it.”

As Bilcik, clutching his face, staggered to the counter for help and bewildered patrons looked on, the suspect first lingered for a few moments before calmly walking out of the eatery at the corner of St. Ann’s Avenue.

Cops are still on the hunt for the suspect.

“This was totally unprovoked,” said Bilcik, who has had one retinal surgery and is slated to go under the knife again for his broken eye socket. “I got bashed in the eye because I’m white.”

Bilcik said he’s now scared to leave his home, but that didn’t stop him Wednesday from hitting up his favorite pizza place.

“I’ve been coming to this pizza shop for 18 years,” he said. “I’m nervous, but I’m not going to let anyone intimidate me to the point where I’m afraid to leave my house.”
