A Sydney CBD restaurant has been fined after staff dumped two incredibly drunk women who'd consumed 16 shots in less than 40 minutes onto the footpath.

Gangnam Station Korean restaurant in Sussex Street is facing a range of sanctions after the incident, which the Independent Liquor and Gaming Authority described as one of the worst breaches of NSW liquor laws in recent years.

Three women entered the restaurant on November 9 last year around 8pm and ordered shots of soju, the Independent Liquor and Gaming Authority said. Each woman drank eight shots in the following 35 minutes.

After each patron drank their eighth shot at around 8.35pm, two collapsed forward and became unconscious.
