After four years on the circuit, GalleyCat knows from book parties—and, let us tell you, cramming upwards of 400 people into Ben’s Kosher Deli Monday night to celebrate the publication of David Sax‘s Save the Deli has to be some kind of record. Which would be fitting, given the number of other world records being set in the room that night—granted, they were all in stunt categories like “most insults flung at a deli waiter in 30 seconds” or “most side dishes ordered in 30 seconds,” but a record’s a record. Sax (left) invited the owners from several of the delis he writes about in his book—a travelogue of the great delis still operating in North America (with a little side trip to Europe)—and brought in Jelvis, “the Jewish Elvis,” for musical entertainment, but you can’t go wrong with a free buffet… especially when it includes hot dogs, knish, potato pancakes, and several flavors of Dr. Brown’s. (And this picture doesn’t even show any of the corned beef or pastrami!)
