Liaw, who was head of legal Asia in The Walt Disney Company's Tokyo-based interactive media group when he decided to take his chances in the amateur chef competition, has announced he'll be opening a Japanese-themed restaurant in Sydney's Surry Hills.

While the exact location of the restaurant is still under wraps, Liaw told the Sydney Morning Herald that an architect is working on the interior and he and his business partner, former Tetsuya's chef Matthew Crabbe, are getting ready for action.

In an interview following his MasterChef win last year, Liaw told Lawyers Weekly he has not entirely ruled out an eventual return to a career in law.

"I definitely haven't ruled out going back to the law in the future, but at the moment there are all these new doors opening up for me and I think I owe it to myself to explore those," he said.

Liaw, who began his legal career at Finlaysons in Adelaide before moving on to Kelly & Co, released his first book, Two Asian Kitchens, earlier this month.
