In New York City’s Lower East Side, where Jewish pushcart peddlers once hawked their wares, is the deli to end all delis. You don’t go to Katz’s Delicatessen for elegant décor. You don’t go for the service. You definitely don’t go if you’re on a diet. But if you’re seeking authentic Jewish deli food that is truly New York, look no farther — corned beef, pastrami, salami, and Nova Scotia Lox. Katz’s operates on an unusual system. To enter the restaurant, you pass through a turnstile and take what looks like a raffle ticket from the cashier. The food is served cafeteria-style; you stand in line and give your ticket to the cooks when you order. They’ll punch the ticket and hand over your food. When you’re finished, just hand your ticket to the cashier and he’ll ring up the bill. The atmosphere at Katz’s Delicatessen is bright, bustling and no-nonsense. The décor is old fashioned without being quaint: salamis hanging from the ceiling, promotional food signs (circa 1960, judging from the color scheme) and autographed pictures of celebrities. There are letters of appreciation from several U.S. Presidents who stopped by for a nosh when they were in the neighborhood. And John Glenn requested Katz’s Pastrami before his ride on the Space Shuttle. A bit of trivia for movie buffs: Katz’s Delicatessen is where they filmed the famous deli scene in When Harry Met Sall.
