Russian Millionaires Spend £130,000 In 'Monumental' Three-Hour Drinking Session In London's Mayfair

The drinkers spent £130,000 in three hours

Two Russian millionaires dropped a staggering £130,000 during a monster three-hour drinking session in one of London's most exclusive bars. The men, believed to be part of the Russian oil industry, stunned bar staff by entering a bet with each other to find out who could rack up the biggest bar tab.

The drinkers, both in their 30s, were accompanied by large entourages and several hangers-on. After 180 minutes, the bar bills read £66,778.91 and £64,279.70 each, amounting to more than 2,000 units of alcohol.

So much booze was bought that a third of the bar bill had to be poured away after the session ended around 3am on Thursday morning. According to bar staff, the men ordered several bottles of vintage champagne. A spokesman for the venue said: "Nobody could quite believe what was happening - the two clients seemed to be trying to outdo each other.

"One ordered five bottles of champagne, so the next one upped it to six, then to seven, and so on. It was incredible. The men didn't end up drinking that much of it themselves - it was mostly consumed by the lady friends they had met inside on the night."

More from the Press Association:

The bar bills included 30 magnums of Cristal Brut champagne, at £1,380 a bottle, 84 bottles of Dom Perignon, 12 bottles of Dom Perignon rose, several shots of 18-year-old Glenmorangie single malt whisky, champagne-based cocktails and bottles of Peroni lager.

The haul also featured soft drinks - 44 cans of Red Bull and 14 bottles of water. The Embassy spokesman added: "The men needed some help drinking what they bought. "It was absolutely monumental. These kind of bar bills are rare, the sort of thing that happens once a year - and then we had two in one night.

"Even for Mayfair, the amount they spent was extremely high." He added: "The two men left in good spirits, they weren't legless or anything like that. But they obviously couldn't drink all they had bought - about one-third was not consumed."

The bill included around £19,000 in service charges, of which the staff take a percentage. "The staff will have done very well out of them," the spokesman said. He said the venue was happy to honour a request from the customers to keep their identities private.
