The owners took to Facebook to thank the community for its support over the "last few days of chaos," before re-assuring everyone that the pub was re-open as of Monday, April 3.

Last Wednesday, a notice taped to the window of the bar at 27-29 East Row informed patrons that the club would be closed for the forseeable future.

Some pub-goers expressed relief that the venue's music and beers would live on, while others joked the temporary closure was a bad April Fool's prank.

The property manager Stephen Royds earlier said the lease had been terminated at 23-25 East Row because the venue was not compliant with fire regulations.

"The owner of 23-25 East Row has terminated the lease due to works conducted by the tenant causing the building to be non-compliant with the current fire regulations," he said in a statement.

"The tenant has been aware for some that that his actions would result in the non-compliance.

But the issue appeared to be resolved by Monday, when the venue owners posted of Facebook, "It's back to gigs as usual at the pub, thanks again to everyone for all the phoenix love over the last week!"

It seems relieved regulars were quick to catch up on their missed dose of live music, with the pub buzzing again by Monday night.

The bar, located in the iconic Sydney building, was damaged by a fire in 2014 that devastated much of the building.
