Alcoholic Architecture is a pop-up bar in Borough Market that contains a cloud of "breathable cocktail" and offers a drinks list entirely made up of spirits and beers created by monks, such as Chartreuse, Trappist beer and Buckfast tonic wine.
The cloud is made up of a 1:3 ratio of alcohol and mixer, and is pumped into the air via heavy-duty humidifiers.
Worryingly, the bar's owners, artistic food studio Bompas and Parr, claim that the alcoholic atmosphere is absorbed into customers' bodies through their lungs and eyeballs.
It's apparently strong enough that visitors will only have to drink 60 per cent of their usual intake to feel the same effect.
For £10 a go (£12.50 after 6PM), customers get "experiences" of 50 minutes in which to make the most of the bar's drinks, alcohol cloud, and church-themed design.
The limited time slots are to make sure that visitors don't get too drunk - one of the bar's designers, Sam Bompas, said that the alcohol "goes straight to the bloodstream, bypassing the liver."
It's not the first time that the bar has appeared in London - in 2009, another Alcoholic Architecture pop-up filled with gin and tonic vapour opened in Soho for a limited time.
It's a trendy place, but you don't need to pay too much attention to your outfit - visitors wear plastic ponchos over their clothes while inside the bar.
Speaking to the Associated Press, Dr. William Shanahan, a consultant psychiatrist at Nightingale Hospital, which specializes in addictions and mental disorders, wasn't on board with the idea.
"The alcohol avoids first pass metabolism in the liver and goes directly to the brain, which makes it much more intoxicating and the intoxication is very rapid," he said.
"This has the potential to cause serious side effects as well as brain damage in the developing young brain."
Dr. Niall Campbell, an alcohol addiction specialist at the Priory Hospital in Roehampton, was even more blunt.
"The last thing this country needs is another way of ingesting alcohol."
