Katz’s Delicatessen

One of the city's few remaining Jewish delis, Katz's has been serving griddled all-beef pups (and world-famous pastrami) since before your bubbe was born. The basic frank ($3.45) is as classic as they come, and the thick-as-your-wrist knoblewurst ($6.85) is a garlicky treat. Kids also love the bustling, only-in–New York atmosphere—check out the signs ("Send a salami to your boy in the Army") and memorabilia plastered everywhere. The restaurant also offers high chairs and booster seats.
