The Golden Opulence Sundae is a sundae that is served by special order at the New York City restaurant Serendipity 3. In 2007 it was listed in Guinness World Records as the most expensive sundae in the world at a price of US$1,000. The restaurant has stated that they sell approximately one per month. It was created to celebrate the eatery's 50th - "golden" - anniversary in 2005. Owner Stephen Bruce states that a notice 48 hours in advance is needed when requesting the Sundae, since the ingredients must be flown in from different parts of the world.
