The Licensed Vintners Association (LVA) has branded as "outrageous and appalling" footage showing a busy Dublin venue serving alcohol to people from a single bottle.
Footage posted on Twitter on Friday shows a party taking place at Berlin D2 on Dublin's Dame Lane with no social distancing being enforced.
A barman can also be seen in the video standing on a bar while pouring drink from a bottle into several people's mouths.
In a tweet, the LVA said: "This is outrageous and appalling. That business should be shut down immediately.
"It is not a pub and does not hold a pub licence."
It also says there is a "clear need for inspections across the hospitality sector to ensure compliance with guidelines & licensing conditions."

Commenting on the footage, Health Minister Stephen Donnelly said: "The vast majority of Irish people have sacrificed a huge amount to help suppress this virus.
"They've shown huge solidarity. People are rightly sickened by these scenes.
"The reckless actions of a small few can have huge repercussions on everyone else."
LVA chief executive Donal O'Keefe said this is very damaging to the hospitality sector.
"I'm absolutely fuming, it's disgraceful behaviour.
"The business in question does not hold a pub licence - we hope the Gardaí investigate thoroughly and that the full force of the law is brought to bear.
"It's simply not acceptable, and it reinforces the need for Garda inspections of all hospitality businesses, because this type of behaviour in a public health crisis is simply not acceptable".
