Founded in 1888, Katz's Delicatessen is an iconic New York institution known for its hand-carved pastrami and corned beef. Made famous by the 'When Harry Met Sally' scene, this Lower East Side landmark serves massive sandwiches 24/7 and maintains its traditional ticket system from its early days. The deli's popularity has only grown over its 130+ year history, with lines often stretching around the block.
