But yesterday, when temperatures started rising above 20°C, the "statement piece" for Vault 21’s 10th anniversary and annual Champagne Long Lunch started to lose shape and re-form as puddles on the footpath.
Vault 21 owner Andre Shi said it made for a fantastic focal point, attracting the attention of both the guests and yesterday’s cruise ship passengers from Anthem of the Seas.
He said a decade ago, he would not have dreamed the restaurant, bar and entertainment venue would be so successful.
"We started out hoping for the best, planning for the worst, and because of our whole team's hard work, we've achieved where we are today.
"We’re delighted to be here today, a decade on."
Last year’s event hit headlines for the wrong reasons when the venue’s liquor licence was suspended for 72 hours, after patrons were filmed drinking Champagne excessively from a Champagne bottle-shaped ice sculpture in the street.
It was labelled an act "at a high level of irresponsibility" by the Alcohol Regulatory and Licensing Authority.
Mr Shi had learned from the incident, and this year’s ice sculpture was a solid fountain, unable to hold Champagne.
"It's an event and an opportunity for our supporters and friends to get together and enjoy a lovely day out," he said.
"Maybe the day is a little too lovely for the ice sculpture — it’s melting."
