While serendipity may be the art of finding pleasant things by chance, what health inspectors found at celebrated eatery Serendipity 3 was not very agreeable.

Officials closed the restaurant Wednesday night after it failed its second inspection in a month. An inspector spotted a live mouse and mouse droppings, fruit flies, houseflies and more than 100 live cockroaches.

"Both inspections revealed rodent and fly infestation and conditions conducive to pest infestation, including stagnant water in the basement," the department said.

People stand in line for hours outside the Manhattan restaurant, known for its extravagant and expensive desserts. Its $25,000 Frrrozen Haute Chocolate features top-grade cocoa, edible gold and shavings of a luxury truffle and was declared the most expensive dessert in the world by Guinness World Records. The eatery also offers a $1,000 sundae named Golden Opulence requiring 48-hour advance notice.
