Serendipity was named after the three legendary princes of the island once known as Serendip (now Sri Lanka), from which the 18th-century writer Sir Horace Walpole coined- serendipity. Serendipity has been popular since the beginning. Marilyn Monroe frequently patronized the restaurant, Andy Warhol was a regular before he was well-known, and First Lady Jacqueline Kennedy was also a frequent guest and once even tried to buy the recipe for the Frrrozen Hot Chocolate for an event she was throwing. Stephen Bruce refused to give her the recipe though he did offer to come and make the frozen drink for her party himself. The recipe can now be found in Sweet Serendipity, a book of recipes and history sold in the general store located inside the restaurant. bye.
