One of the city’s longest-running success stories, Katz has been in business since 1888. You may feel a sense of déjà vu as you enter, as this is where Meg Ryan, ahem, made a scene in When Harry Met Sally, and it looks just as it did in the flick: a cavernous, loud space with linoleum-topped tables; celebrity photos and testimonials plastering the walls; and curtains of hanging salami in the window. Though its menu is varied and long, only the uninitiated bypass the corned beef sandwich ($17)—the best in the city—a towering stack of meat cured for as long as 30 days, which gives it a richness and depth that you simply don’t find with commercially prepared corned beef (which is “pressure injected” to cure in a mere 36 hours).
