Pizza World Records

The largest pizza was at the Norwood Pick 'n Pay hypermarket in Johannesburg, South Africa. According to the Guinness Book of Records the pizza was 37.4 meters in diameter and was made using 500 kg of flour, 800 kg of cheese and 900 kg of tomato puree. This was accomplished on December 8, 1990.
In Feltham, London, a record for the farthest food delivery was achieved by Lucy Clough of Domino's. A vegetarian supreme pizza was cooked on November 17, 2004 and travelled 10,532 miles (16,950 km) to its delivery point in Melbourne, Australia, on November 19, 2004. The record is in the 2006 version of the Guinness Book of Records.
The most expensive pizza was made by the restaurateur Domenico Crolla, which included toppings such as sunblush-tomato sauce, Scottish smoked salmon, medallions of venison, edible gold, lobster marinated in the finest cognac and champagne-soaked caviar. The pizza was sold at auction for charity for £2,150.
What has been called "the world's most extravagant pizza" is available at New York's Nino's Bellissima restaurant. Topped with six varieties of caviar, chives, fresh lobster and crème fraîche, this 12-inch (30 cm) pie, called the "Luxury Pizza", retails at US$1,000.00 (or $125.00 a slice).
