Ferrier Hodgson said the board of the Keystone Hospitality Group couldn’t reach an agreement with the lenders on key aspects of its financial structure.

The group’s assets, which include Jamie’s Italian restaurants in Adelaide, Sydney, Perth, Canberra and Brisbane, may be sold as a whole or broken up.

The Adelaide restaurant, on the corner of King William Street and North Terrace, opened in September 2014.

Celebrity chef Oliver came to the city in March the following year to meet the staff, as well as visiting his “Ministry of Food” project in the southern suburbs.

At the time, he told InDaily that the Adelaide Jamie’s Italian – one of a string of such restaurants all over the world – was instantly recognisable: “It’s sort of like your genetics are all over the place – all the little decisions that have been made … it really does feel like home”.

Keystone Hospitality Group receiver Morgan Kelly said the Australian Jamie’s Italian restaurants would continue to trade as usual until sold.

“Given the current buoyant hospitality market, we anticipate a lot of interest in the sale of the venues,” Kelly said.

The Keystone Group website says the company was founded in 2000 with the opening of Cargo Bar, which was popular with locals and international revellers during the Sydney Olympics.

Oliver – whose career took off with his popular cooking show The Naked Chef – established the Jamie’s Italian chain in partnership with his mentor, Italian chef Gennaro Contaldo (whom InDaily interviewed at the time of the Adelaide restaurant opening).

He has also set up numerous programs to improve the quality of supermarket food, and teach people to cook and grow nutritious food.
