The deli in "When Harry Met Sally" is Katz's Delicatessen, a famous Jewish deli in New York City. The iconic deli scene features Harry and Sally reconnecting over lunch at Katz's Deli, where Sally famously fakes an orgasm to prove a point, leading to a nearby customer saying, "I'll have what she's having." In the scene, Sally orders a turkey club sandwich, and Harry orders a pastrami sandwich. The moment is humorous and memorable, symbolizing their complicated relationship and the film's exploration of romance and friendship.
Billy Crystal, who plays Harry, has mentioned in interviews that he personally enjoys Katz's hot dogs and even orders them with specific instructions inspired by the film's setting.
The deli remains a cultural landmark largely due to this film scene and has been revisited both by the actors and in various media related to the film.
