Gastro Park, Potts Point, is the latest high end restaurant to close

Gastro Park, the award-winning Sydney restaurant with the controversial name, is closing with its last service on May 20.

The butt of gastro jokes since opening, Gastro Park's chef-owner Grant King has also earned lashings of praise and plenty of chef's hats for his innovative, upmarket food.

"Obviously there's the gastro (joke) but it also has the gastronomy connotation. We also have simplicity on the menu, and I don't want people expecting some sort of wizardry with everything they eat. It'd be nice to just get a best piece of local produce," he says.

King plans to reboot the Potts Point restaurant with a new name and direction, but insists fine dining in Sydney isn't in its death throes.

"It's been six years since we opened. I'm just a little operator doing it on my own. We all need a fresh change. It's a change in ethos," he says.

"I've been contemplating a lot of things. And I do have plans to open other places," he tells Good Food.

And the name of the new restaurant? The chef will reveal it in coming months, but don't expect gastro in the title.
