ONE of Toowoomba's most popular fast food destinations has shut its doors.

Charcoal Chicken at 185 Margaret St has long been the place for people enjoying lunch or a late night out in the CBD to grab a bite.

But now the doors are shut, with just a handwritten sign on the door announcing its permanent closure.

The sign reads, "Apologies, Charcoal Chicken is permanently closed. Finished, shut, gone".

The long-standing business had hit the market to be sold in December last year, with owners of the past seven years Vicki and Michael Green citing her ill health for the sale.

However, they had said things would not change in the store when new owners arrived.

The owners had embraced Toowoomba's late night revellers, with no designated closing times on Friday and Saturday nights. The chicken and chips in salt, gravy and cheese was a crowd favourite.

The owners have been contacted for comment.
