Spending watchdog the Audit Commission spent £20,000 in the past two years on luxuries such as meals in Michelin star restaurants.
The Commission, whose mission statement is to drive economy, efficiency and effectiveness in public services, allowed officials to use corporate credit cards to pay for fine dining, cinema tickets, doughnuts, clothing, gym equipment, sweets and music from HMV.
Officials spent hundreds of pounds at Marco Pierre White's L'Escargot, frequented by Rolling Stones frontman Mick Jagger, as well as a brasserie owned by celebrity chef Raymond Blanc, the Daily Mail reports.
In the past three years, the body, which is due to be axed in the government's quango cull, spent £4.7m alone on hotel rooms for staff.
Local government minister Grant Schapps said: "It seems the Audit Commission was not applying checks and balances on itself that it preached to councils.
"What is so disturbing is that their expenses read like a shopping list for some lavish party."
The figures were revealed in an answer to a parliamentary question by conservative MP Eric Ollerenshaw.
An Audit Commission spokesperson said; "In common with many public bodies the Audit Commission uses government procurement cards for low value transactions or where a purchase order is impractical.
"Between April 2008 and March 2010 we processed 8,818 transactions at an average cost of £125. All purchases were for legitimate business purposes.
"Payments made by these procurement cards are routinely checked to ensure the cards are being used correctly."
