This is the moment a restaurant patron was so drunk they tumble backwards in their chair and struggle to stand up.

Now the licensee of the Korean restaurant in Sydney’s CBD is facing disciplinary action over the incident that saw two patrons became so intoxicated they were later found passed out on the road and footpath outside the venue covered in vomit.

The male and female patrons were part of a group of five who NSW police allege were served up to 86 standard drinks of Soju over six hours at the Haru Fusion Soju Lounge in October last year.

Soju is a Korean drink that has an alcohol content between 16 and 53 per cent.

Police said they attended the venue about 1.35am on October 11 where they found an unconscious woman outside the restaurant next to a pool of vomit, and an unconscious, man covered in vomit nearby.

The man had earlier been lying unconscious on the road before being moved to the footpath by road workers.

Police said the pair was part of a group of two women and three men who took part in a six-hour drinking session at the restaurant to celebrate a birthday.

CCTV footage showed a female staff member simply walk past a male patron sleeping at a table in the restaurant without taking any action.

The woman found unconscious on the footpath was carried from the venue by two other patrons.

The pair had to be taken to hospital as a result.

The NSW Independent Liquor and Gaming Authority has imposed a strike against licensee Chris Chang under the government’s Three Strikes disciplinary scheme, and is considering further action against the Castlereagh St venue including winding back its trading hours.

Authority chair Philip Crawford said it would be hard to find a more serious case of a venue showing blatant disregard for responsible service of alcohol obligations.

“It is almost beyond belief that venue staff could serve such a large amount of alcohol to a group of five patrons and not take any steps to avoid extreme intoxication,” Mr Crawford said.

“The fact one of the patrons was passed out on the road highlights the risk of serious injury or death.

“The Authority will consider imposing a range of special conditions on the venue’s liquor licence, as well as winding back the venue’s trading hours.”

Licensees with strikes face a range of remedial action and those incurring three strikes can have their licences suspended or be permanently removed from the industry.
