SUZANNE CHESSLER Special to the Jewish News L ast month, after Rabbi Shmuley Boteach served a Michigan audience morsels from his non-traditional best- seller Kosher Sex, he headed out for morsels of kosher food at the non-tra- ditional La Difference (accent on last syllable) a gourmet restaurant in West Bloomfield. Instead of putting gefilte fish on his plate, the author-rabbi discovered bar- becued ahi tuna with a sauce of apple curry and raspberry essence. "The food tasted so good you would have thought it was treif;" joked the rabbi, who left behind a. clean platter. "The rabbi is Orthodox, and he was hungry," says La Difference owner Paul Kohn, who has opened Jewish palates to flavors from many other cultures in . his kosher fine dining establishment. "It was so nice to be able to accommo- date him." Open more than a year ago, La Difference offers a menu to attract people who do not adhere to Jewish dietary laws as well as those who do. Kohn has been expanding his dairy menu and service options to hopefully build a stronger customer base and turn the operation into a profit-mak-- ing enterprise. The restaurant is now helped along with earnings from Kohn's core business, the Southfield- based Quality Kosher Catering.

Although the rate of return is not writ- ten in black ink yet — and well aware of previous kosher restaurants that did- n't survive the pressure of turning a profit — Kohn nevertheless believes there has been progress at La Difference. And he's hoping to bolster that with some new dishes and services this summer. A new $16,000 point-of- sale system has been installed to help crunch the numbers. "The numbers that are encouraging show a difference between the first five months of this year and the first five months of last year," says Kohn. He also is encouraged by La Difference's 7/14 2000 43
