"Shanghai has a tradition of enjoying pork-filled mooncakes. But with our famous steakhouse, we decided to use our Australian wagyu beef to whet people's appetite. Before it hit the market, we were still worried beef wouldn't sell," said Wang.

On Nanjing Road, a line forms outside the traditional Cantonese Xinya Restaurant as impatient customers hanker after its newly launched yanduxian mooncakes. Taking inspiration from Shanghai's beloved yanduxian soup, which is made from pork and bamboo shoots, the mooncakes were a hit as soon as they were launched.
