At A$138, the 150-slice pizza is a lot of dough and it's on sale to the average Joe.
To take the title "The Big One" as its known has to be on the menu continually.
The pizza hopeful measures about a metre by 1.25 metres and takes up nearly all the space in the shop's brick oven.
At less than a dollar a slice anyone who orders The Big One is getting a bargain.
But Mama Lena's Pizza House say they’ve had few takers so far.
Perhaps some free garlic bread and bottle of Coke will clinch the deal.
