In 2007, owner Stephen Bruce of Serendipity 3 in New York City set out to get a Guinness world record for most expensive dessert for the $25,000 Frozen Haute Chocolate Sundae. What makes it so pricy? It includes a blend of 28 cocas, and is infused with 5 grams of edible 23- karat gold and served in a golbet lined with edible gold. Customers even walk away with an 18-karat gold bracelet with diamonds and a gold and diamond encrusted spoon and goblet set..!!
