A popular Sunshine Coast patisserie is not French enough and does not have any macarons, according to a complaint made to the Office of Fair Trading.

Sunshine Coast GP Corinne Aveline also lodged an online petition complaining some businesses on the coast "pretend cooking French" when "in fact they just put fancy names and charge 10 times the price".

So far, she is the only signature on the petition.

Eric Pernoud, a Frenchman and the owner of La Maison du Patissier in Meridan Plains, said Dr Aveline's complaints began when he opened up his new shop after moving from Cooroy.

"First we didn't have any creme brulee, because we couldn't find proper dishes, then she says our croissants taste like IGA croissants," Mr Pernoud said.

Mr Pernoud claims she has complained about his shop on social media.

But it was the macaron faux pas that has caused the biggest stir, with her taking her complaint to the Office of Fair Trading.

"I call the shop to know what food they sell [and] they told me to look on their website," she wrote in her statement.

"Then when I arrived in their shop there was no macarons [and] no creme brulee as advertised on their website so I bought some croissants, two operas, a chocolate cake, a batard bread, and a French stick.

"If my memory is good I have friends at home this night and we were all very disappointed with the chewy bread, the brioched croissant, and the operas."

She has recommended to the Office of Fair Trading the business "not pretend to bake fresh bread and French food" and decrease its prices.

She has also requested a $40.50 refund.

Macarons going out of fashion in France: Pernoud

He said he decided to scrap macarons from the menu as he had been making them for many years at his former patisserie in Cooroy and thought it was a time for a change.

"I've been making them since the 80s but I don't like them — they are very sweet and use food dye," Mr Pernoud said.

"I thought new business, new beginning, and I spent three months in France where it seems they were going out of fashion."

Mr Pernoud said he could not believe it when the Office of Fair Trading gave him a call to inquire about his alleged false advertising.

"She wants her money back on something she ordered because we didn't have the macaron and then accused us of false advertising on the macarons," Mr Pernoud said.

"It's just ridiculous."

Macarons were not used on any of his current advertising and he said she may be referring to another web page which was "five years old".

Mr Pernoud said he had no plans to pay the money back.

The Office of Fair Trading said it could not comment on specific details of the case.

Dr Aveline could not be reached for comment.
