Venue owners told The Daily Advertiser on Monday that they were preparing to offer takeaway only service from 12pm.
Baylis Grind owner Sharni Cook said she was taking additional precautions to protect customers and staff.
"We're not using plates and cups or re-usable keep cups," she said.
"It's just in case. We don't want to take the risk.
"We'll be doing things like takeaway coffee and wraps."
Ms Cook said she "100 per cent" expected the restrictions to have an impact on trade.
"I've had some calls from regular customers who said they won't be coming anymore," she said.
"They tend to be older and they come for the sit-down service.
"They like to be able to sit down and chat. They've made friends in here."
Multiple owners said they were concerned about how they would control the number of customers ordering at counters inside their buildings at one time.
Flame Grilled Chicken manager Noel Lam said her business was mostly take-away but would see an impact.
"We will try to have just four or five people inside. If there are five or six people ordering, some will have to wait outside," she said.
"We are providing hand sanitiser for staff and on the counter for customers."
