Katz's Deli is the setting for the most famous scene in Nora Ephron's film When Harry Met Sally.  At the end of the scene between Meg Ryan and Billy Crystal, Sally fakes an orgasm to prove to Harry that it can be faked.  When she is finished, another customer delivers the line, "I'll have what she's having."  (The customer was played by Estelle Reiner, director Rob Reiner's mother.)  Nora Ephron's screenplay was later nominated for both an Academy Award and a Golden Globe and is just one of Ephron's many achievements in an industry dominated by powerful men.  In addition to writing (Silkwood, Sleepless in Seattle), Ephron has found success as a film director with several hit romantic comedies to her credit, including You've Got Mail and Julie and Julia.
