Sandwich lovers in London are about to get a seriously tasty lunchtime upgrade as Heinz launches the UK’s first-ever “AutoMayoMat” in Soho this June.
Created to celebrate Britain’s obsession with sandwiches and the return of proper lunch breaks, the immersive self-serve sandwich vending experience will serve freshly made sandwiches packed with Heinz Mayo for just 57p.
The Heinz Mayo AutoMayoMat lands at 15 Bateman Street in Soho on 17th and 18th June 2026, perfectly timed to coincide with National Picnic Week. Visitors can expect over 800 freshly prepared sandwiches inspired by iconic British lunch favourites, all layered with Heinz Seriously Good Mayo.
Heinz Wants Britain to Take Back the Lunch Break
According to Heinz, the UK consumes an estimated 11.5 billion sandwiches every year — roughly 380 sandwiches every second — proving the humble sandwich remains one of Britain’s favourite meals.
However, despite the nation’s love for a good sandwich, lunch breaks themselves are becoming increasingly rare. Heinz says more than half of Brits admit they rarely take a proper lunch break, with meals often eaten at desks or squeezed between meetings.
The AutoMayoMat has been designed to encourage people to step away from their screens and enjoy a proper lunch moment again.
Inspired by the nostalgic European automat culture first introduced in Berlin in 1895, as well as the convenience-store sandwich culture of Japan, Heinz has reimagined the concept with a distinctly British twist.

What Sandwiches Will Be Available?
The Heinz Mayo AutoMayoMat menu has been created in collaboration with cult-favourite sandwich brand Sandwich Sandwich.
Each sandwich will be freshly prepared and dispensed from individual self-serve compartments. Guests will also receive a personalised engraved lunchbox, tote bag and a bottle of Heinz Seriously Good Mayo with their purchase.
