A Brisbane restaurateur has issued a warning to others after she says she was scammed by a group of women claiming to have found glass in their food.

Birds Nest Restaurant owner Marie Yokoyama posted a warning to her Facebook page on Tuesday morning, more than a week after the group of three women, along with their four children, got out of paying a $180 bill.

Her post has since gone viral, with hundreds sharing her message.

It appears she is not alone, with the Restaurant and Catering Industry Association (RCIA) saying they were aware of a few cases from members who went through similar experiences.

Speaking with ABC News, Ms Yokoyama said the group came into her Fortitude Valley restaurant last Monday about 2:50pm.

"Halfway through the meal one lady started screaming that there was glass in her meal and that her mouth was bleeding," Ms Yokoyama said.

"I was pretty confident the glass hadn't come from us. I was trying to match where it might have possibly come from in the restaurant and I couldn't find anything."

Ms Yokoyama said at the time she apologised and gave them their meals and drinks for free.

"I told them I'm sorry and cleared everything away from the table, thinking they were going to leave. Then she comes back after having a cigarette and says, 'where's my drink?''

"I poured them another round of drinks and they came up to my face and said: 'I'm really traumatised, I'm really traumatised. We were going to come back here but we not going to come back, we were going to bring more people back.'

"It's pretty full on. I felt intimidated."

Ms Yokoyama said she eventually asked the group to leave, saying the women were so rude and demanding, and their children were screaming and running around the restaurant.

"It's the first time I've had to do that," she said.

"I just literally stood there like a broken record saying: 'Get out of my restaurant."

"I've never had anything like this happen to me in my life. It's intense."

'There are a number of scams targeting small businesses'

Ms Yokoyama said since her experience she's learned of at least one other Brisbane restaurant she believes fell victim to the same group.

"They ordered steaks and prawns, and then half way through the meal claimed there was glass and demanded it for free," Ms Yokoyama said.

Ms Yokoyama reported the incident from her restaurant to police on Tuesday afternoon.

A spokesman for the RCIA said they were aware of a number of similar scams targeting small cafes and restaurants.

"We are continually monitoring this situation," the spokesman said.

"We always advise our members that they should beware of such scams and to always make a decision based on the veracity of the claim or complaint before being caught up."

Brisbane City Council said it has not received any complaints about glass in food at Birds Nest Restaurant.
