The most complete vision yet of Yagan Square — the long-promised project to connect Perth CBD with Northbridge — has been revealed ahead of its opening to the public next month.

The project is on track for its mid-February opening and on Monday more local food and beverage vendors were announced to set up shop in the public space.

Yagan Square is part of the previous Barnett government's Perth City Link plan and will showcase about 20 food vendors, a digital tower and a rooftop water feature for children.

Six more vendors, set to operate out of Market Hall, have been added to the 10 tenants already announced last year.

Those include Shy John Brewery and Yum Cha, Street Eats restaurant, Sue Lewis Chocolatier and Honeycake.

Planning Minister Rita Saffioti has promised it will be an affordable place for West Australian families to visit.

"There's all these different type of options … because of the access and because of the range of food here available, I think it will be affordable for families," Ms Saffioti said.

She said the broad range of locally-based vendors would draw crowds to the precinct for the unique experience.

"This is very similar to what you experience when you go overseas and go interstate and this is something I want to see happen in Perth," she said.

"It's basically a new heart [of the city]."

Tourism Minister Paul Papalia said a more relaxed attitude towards alcohol service, which allows drinks to be served at a number of the outlets, will encourage a "more European culture of drinking".

"[We want to] pursue liberalisation of liquor legislation with a view to changing, encouraging small innovators and smaller outlets," Mr Papalia said.

"[And] changing, over time, changing the liquor consumption culture of Western Australians."

The Australian Hotels Association has backed the Government's more relaxed view on alcohol service, but chief executive Bradley Woods said it needed to go further.

"What we need to see is that there's a broad sweeping change in liquor licensing laws in WA to reduce some of the red tape and regulation on businesses, particularly where it's costing them a huge amount in legal fees and unnecessary compliance costs," he said.

"We'd like to see the Government's priority agenda for 2018 be the relaxation of red tape and regulation on existing and new hospitality operators."
