"Send a salami to your boy in the Army!" was the wartime slogan of Katz's Delicatessen, an institution on New York's Lower East Side since 1888. Even if you don't have a boy (or girl) in the armed forces, a Katz's salami is a one-of-a-kind New York memento. And the best part: When you stop in to buy it, you can treat yourself to the city's finest pastrami sandwich, still served in gloriously idiosyncratic fashion along a sandwich-making assembly line that would make Toyota proud.
