Promotors of last night's pilot nightclub event at the Button Factory in Dublin say they feel it was very successful.
David Parle of Hidden Agenda Promotions said that once people got inside the building in Temple Bar it felt like a "normal" night out.
He said the 450 attendees wanted to bond with others, see people they had not seen in a while, and that "hopefully we are nearly there with that".
Mr Parle said that as the event was a pilot one, it was important for antigen testing to be carried out to prove that the event could be carried out safely.
However, he said the testing took a lot of work, and involved hiring extra staff as well as a separate building to carry out tests throughout the day.
Mr Parle said he was not sure how practical that would be for more widespread usage but said he hopes the Government will give direction on that.
Minister for Arts Catherine Martin said a report on the use of antigen testing is expected shortly.
No positive Covid-19 tests were reported last night.
The Department of Arts said that attendees will be contacted in the coming days to see if any infection occurred as a result of the event.
