Infamous Karen’s Diner in Adelaide appears to be closed after interstate locations shut doors

The American-style eatery which boasts “having the worst service in the world” closed stores in Melbourne, Perth and the Gold Coast last week – is Adelaide next?

After an American-style chain restaurant known for its “rude service” closed three of its locations around Australia, the Adelaide CBD location of the business could be in jeopardy.

The diner, located on East Tce, appears to have shut up shop after having opened in Adelaide on December 1.

There were stacks of chairs, scattered tables and no signs of life at the iconic restaurant on Tuesday night.

This comes after locations in Perth, Melbourne and the Gold Coast closed last week.

The status of the Adelaide store – which we reviewed around the time of its opening – remains unclear as it is listed as “permanently closed” online.

Other than the Adelaide location, only one store in Brisbane and two in Sydney remain open.

“Unfortunately, all good things come to an end and Karen can’t stay forever!” read a post on the chain’s Facebook page from last week.

“Today marks the closing of some of our Australian pop-up stores.

“If your local pop-up store has closed, there will be a Karen’s Diner On Tour coming to your city this September.”

Karen’s Diner has been forced to apologise in the past after staff took their rudeness act a little too far.

In July, an employee at the Brisbane store made sexually inappropriate comments to a 14-year-old girl and her father.

And in November, the ABC reported staff were considering formal action over claims of sexual and physical harassment.

The “Karen” in Karen’s Diner comes from the derogatory term for an entitled person who is often rude to those in service industries, likely to demand a manager to register complaints over minor slights.

The chain also has stores in Indonesia, Singapore, New Zealand, the UK, Canada, and the US.

The Advertiser has contacted Karen’s Diner for comment.
