[In the voice of Don LaFontaine] "In a world of açai and gentiles, where the pastrami sandwich is the twin victim of anti-cholesterol fanatics and anti-Semitic zealots, one man has decided to save the great but endangered institution, the deli." That man is David Sax. Young Sax created a blog called Save the Deli, and now has a book, also called Save the Deli. Sax, who’s written for nymag.com, has even made a video trailer of the book of the blog. Coming on October 19 to a bookstore near you.
