  Price of the most expensive restaurant meal ever:

$62,679
To celebrate a business deal in the summer of 2001, 6 Barclays traders took what began innocently enough as a £50 per-head meal at Gordon Ramsay's Petrus in London, and took it to new, ill-advised heights, the group had four bottle of wine, including one which cost $16,500 and is considered the greatest wine ever made. The restaurant was so impressed with the largess of the Barclays group that it wrote off the actual food bill, which totaled about $569. Barclays was less impressed however, and even though the traders made no attempt to charge the meal to their expense accounts, Barclays had recently laid off workers, and the excess was thought to be unseemly. Five of the six diners lost their jobs as a result of the meal.
