Patrons were forced to run from Mosman Rowers Club this morning, after a blaze broke out on the lower level just after 10:30am.
More than 40 fire fighters were called to the Mosman Bay landmark, as plumes of smoke billowed from lower level windows of the new Archie Bear café.
The waterfront venue re-opened just two weeks ago, after a near-death experience that saw the 108-year-old club slip into administration in 2018.
Local resident Jeanette Cox was at the cafe with her husband, when she noticed flames in the weatherboard cladding outside the club.
“It all happened very quickly and we were worried the whole building would go up,” she said.
“There was a long wait for the first fire trucks to arrive though, and we had to phone three times to check that they were on the way.
“It was a very worrying situation and the staff did an excellent job trying to hold off the blaze.”
