Christian icons are scary to non believers. Who wants to walk into an Italian restaurant and see a carving of some guy being crucified? It is not surprising that trad Italian restaurants can be kinds scary if you are not a Christian.
Arthur Schwartz, writing in EGullet says:

“That Jews have an affinity for Chinese food is no secret. The Jews know it. The Chinese know it. Everyone knows it. Until the dispersal of middle-class Jews to the New York suburbs was complete in the 1970s and 1980s, Chinese take-out shops opened on every corner of the city. It was said that you could tell how Jewish a neighborhood was by the number of Chinese restaurants.”
