It is difficult to unravel the link between food and sex. If it didn’t lead to sex, I probably never would have botehred becoming a good cook or an exprt at eating out while in London. In The Observer Kathryn Flett and Alex James discuss “the joys of nude bubble and squeak, desert sex and why Last Tango in Paris should be full-fat only”.

James:

“Food and sex are close cousins. Our enjoyment of both depends upon who else comes to the table. Food shopping for one is more depressing than masturbation.”

Flett:

“Well, bad food is often worse than bad sex because women are quite often primed for bad sex but remain terribly disappointed by a crappy meal. And bad food cooked for you by the person who is also responsible for the bad sex is, probably, inevitable.

Good food, meanwhile, is obviously much better than bad sex, though good food is sometimes even better than good sex, especially while pregnant. And of course it goes without saying, though I shall say it anyway, that fabulous sex is better than almost everything… except great food cooked for you by someone with whom there is also the prospect of having fabulous sex.”

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.”
