To further commemorate the film, Hellmann’s teamed up with Katz’s Deli. Through Sunday, February 9, they are offering a "What She’s Having’ Sandwich" Package which includes recipes, Hellmann’s mayonnaise Katz’s turkey and their famous hand-carved pastrami with fresh rye bread. Visit katzsdelicatessen.com for more details.

The movie's memorable Katz’s Deli scene arguably features its most famous line: “I’ll have what she’s having.” In fact, Crystal and costar Meg Ryan even recreated the iconic rom-com moment for their new Hellmann’s Super Bowl ad.

Is the OG rom-com coming back to fans? Well, the queen of the genre herself, Meg Ryan, caused quite the stir when she posted a photo of herself with her When Harry Met Sally costar Billy Crystal on Wednesday,

When I opened my Instagram feed and saw a picture of Meg Ryan and Billy Crystal together again, my first reaction was "AH!" — especially since they're sitting on a couch, just like they do at the end of When Harry Met Sally.

"When Harry Met Sally..." co-stars Meg Ryan and Billy Crystal are teasing a big announcement. The stars of the beloved 1989 film hinted at a future collaboration in a joint Instagram post Wednesday. "It's finally happening, we're reuniting for something iconic," Ryan wrote in the caption of the post. "Can't wait to show you all soon 💙."
