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.
