2009 MasterChef winner Julie Goodwin - host of Home Cooked! With Julie Goodwin.

Keeping it real ... Julie Goodwin will be wielding pans at the pop-up Masterchef restuarant, with all donations going to charity.

IN A further blurring of the line between reality TV and reality, a MasterChef restaurant is set to open in Sydney.

The pop-up restaurant and bar, MasterChef Dining, a joint venture of the Ten Network and the media production company Shine 360, will be built in the forecourt of St Mary's Cathedral and open from July 3 to 22, with funds raised going to the OzHarvest charity.

The public will be able to book seats as if for a regular restaurant. No cameras will be recording the kitchen or dining room and the pots and pans will be wielded by past MasterChef stars Julie Goodwin and Marion Grasby, plus a string of other chefs including Justin North and Kylie Kwong.

Despite the temporary nature of the restaurant, the eatery will be housed in a purpose-built two-storey building designed by architect Kelvin Ho.

"The forecourt of St Mary's Cathedral will be an amazing backdrop for this,'' Shine's Petrina Baker said. ''It's set to be an incredible dining experience for foodies and fans alike."

Bookings will be available from June 20 from the MasterChef website.
