Phillip Hogan, the co-owner of the bar, said the crown prince "seemed to be a very nice guy".
This is just the tip of the iceberg with the Prince.
Perhaps they'd best ask the Crown Prince of Denmark for his thoughts on the matter.
Mr Hogan said he feared once the publicity about the prince's visit had passed he would be fined for allowing him to enter. "We did everything we possibly could", he said.
According to News Corp, the officers told the bar that Crown Prince had permission from the Office of Liquor, Gaming and Racing (OLGR) to bypass ID laws and was eventually allowed entry.
They'd gotten this inside 15 minutes, at around midnight on a Friday.
"We're dealing with it all the time with normal people without ID, and if you're not someone like Prince Frederik, you don't hear about it", he said.
Health Minister Cameron Dick stood by the ID scanning laws, saying there were "doing what we want them to do" and preventing alcohol-fuelled violence.
However, Queensland Attorney-General Yvette D'Ath saw the bright side.
Mr Stewart said the visiting royal was never refused entry and the identification issue was resolved during two earlier meetings involving the Prince's entourage.
After finally gaining entry, Prince Frederik broke away from the security detail and fronted up to the bar on his own.
"The fact is this has not caused a diplomatic incident as some would have you believe".
"I think Queenslanders like the idea that everyone, regardless of whether they are a prince or an average man or woman on the street, I think that Queenslanders like that everyone is treated the same under the laws of our state", he said.
Gresham manager Ryan Lane said called the laws "embarrassing" after the club was forced to turn away a group of French winemakers, aged between 40-65 years old, who were not carrying identification in July.
But Mr Kilvington said it was a symbolic gesture.
He's used to being welcomed with smiling facing and warm greetings wherever he goes, but Danish royal Prince Frederik got a rude shock when he tried to enter an upmarket bar in Brisbane on Friday night.
"It's not going to get rid of scanning, but there's an enormous amount of work involved in running an incorporated body", he said.
