The Scottish brewer and operator's Edinburgh, Sheffield, Shepherd's Bush and DogTap (at the Ellon brewery headquarters near Aberdeen) branches will offer up to six toppings on each £9 pizza.
On its website the craft firm said: "We are well and truly into summer now and on days when the sun filters over the rooftops, the last thing you want to do is stay at home and wrestle with the contents of your kitchen cupboards.
"We get that. So, four of our UK bars have recently introduced an amazing new pizza menu to remove that unwelcome surprise from your itinerary."
