Billy Crystal and Meg Ryan star in a brand-new Super Bowl advertisement that calls back to their iconic deli scene in "When Harry Met Sally."

The commercial, which also features a cameo appearance from Sydney Sweeney, was shot at the same table in Katz’s Deli where the classic 1989 rom-com was filmed.

It’s a reunion 35 years in the making, thanks to mayonnaise. More than three decades after the romantic comedy “When Harry Met Sally” first hit theaters, Billy Crystal and Meg Ryan are finally back together.
