The NSW Government's roadmap states only fully vaccinated people will be able to dine in at cafes and restaurants once the state starts to re-open after hitting the 70 per cent vaccination rate. The re-opening begins on Monday.

But, Xen Cafe in Brookvale and Bare Wholefoods in Mona Vale, both on Sydney's northern beaches, say this is discrimination.

"They [the NSW Government] have publicised it under the guise of the greater good, but when the vaccine doesn't stop transmission, even though it might slow down hospitalisations, I really think it's discrimination," Xen's owner Candice Shields said.

Ms Shields and her staff are vaccinated "by personal choice", but she said her customers have the right to "dine in without judgement, discrimination or invasive questions being asked". She also fears her staff may be abused if they refuse entry to the non-vaccinated.

"I've seen a few videos from the USA where they've verbally abused staff for not letting them in," Ms Shields said.

Bare Wholefoods' Anthony Milotic said he would not stand for segregation in his cafe.

"Choosing love, accepting differences and a community in unity is what we need right now," he said.

"We have chosen to continue to operate as takeaway only until everyone is free to dine in. I want everyone to feel welcome at all times and I will never put profit before people."

The proposition of having to refuse entry to non-vaccinated customers will likely not be a factor for Hugos Manly, with the business still crippled by COVID restrictions, owner Dave Evans said.

"The restriction of one person per four square metres makes it unviable when we've still got to pay our staff the full money," he said.

"I reckon I'd lose $30,000 to $40,000 a week. It's just a matter of how much more money am I willing to lose."

Mr Evans said the reduced capacity restrictions worked last year thanks to JobKeeper, but this around "it's not worth opening the doors".

"We probably won't open until December 1, so we won't have to discriminate between someone who's vaxxed and someone who's not," he said.
