Broad Street's depressing downward spiral over the last decade sparked the forum's most fraught debate at the first in the new series of The Birmingham Post Business Property Forums.
Most outside observers blame the local authority and the bar owners for creating the testosterone-laden and alcohol-fuelled nocturnal environment.
The forum's chairman, Peter Burford, certainly had no doubt where the responsibility lay.
"The city council forced Broad Street down into the bottom of the gutter before it allowed it to rise," he said at the Birmingham offices of CB Richard Ellis.
The first contributor to agree that the area had to change was the council's planning director, Emrys Jones.
"At late night young people are drinking to excess and all the anti-social disturbances, and noise and other problems flow from that," he conceded.
He saw merit in Planning Minister Keith Hill's recent decision to introduce a new classification system for High Street premises this summer. Until now owners of restaurants, pubs and takeaways have been able to change into one of the other uses without planning permission.
"This proposal tries to give local authorities more control. We certainly want to stop the mono-culture developing and we need to be more inclusive, like many cities on the Continent," said Mr Jones.
He admitted though that the city council had encouraged the evolution of Broad Street in its present form, and that many shops and restaurants had been squeezed out.
"At the time we were not so keen to promote city living," said Mr Jones. St Modwen's Derek West suggested that most quality outlets were reluctant to open up in the area because of the threatening late-night atmosphere. The paradox that Broad Street was also home to such major venues as the ICC and the NIA and several upmarket restaurants was also explored.
"I know people who have left a CBSO concert, started to drive home, taken the wrong turning and found themselves in the middle of nowhere," said Mr Jones.
Wisely he didn't detail their resultant experiences, though other forum members were in no doubt. CB Richard Ellis's Jason Tait saw shadows in the debate about categorising premises.
"Take All Bar One at Brindleyplace. At lunchtime the customers are mainly eating. At night, they are mainly drinking. Is that a bar, or a restaurant?" he asked.
Others considered the debate to be more clearly defined though, describing Broad Street as "a ghetto".
M & B's Clive Radford naturally disagreed with that perception, but then floated the idea of creating a designated zone for late-night drinkers.
"They do spend a lot of money and the business is worth having, so you have to accept that the market exists," he suggested.
"You might wish to relocate it somewhere else where you could control it."
The distinction between a ghetto and a dedicated drinking area was too fine for most observers, but Mr Jones had the answer.
"The polite term is that you are creating a leisure quarter."
