The family-run sandwich business, which has three locations in Bristol, will take over the first in Tossed, at the junction of Gresham Street and St Martins Le Grand.
News of Sandwich Sandwich’s first London location comes after the company, led by Josh Kleiner, was named Restaurant of the Year by Uber Eats in the UK and Ireland in October, winning a £100,000 award for making an investment in the business.
“I can’t allow this to be happening,” Kleiner wrote on Instagram.
“I think it’s what other people would describe as a ‘pinch me’ moment.
“Honestly, I can’t express how excited and nervous we all are. Naturally, I focus on the dangers involved in this decision, but the love and love we receive every day tells us that this is the right decision. “
Sandwich Sandwich was founded by Kleiner’s father in 2010 as Gotham Sandwich Co.
It replaced its call in 2012 as part of its expansion goal in Bristol and has since opened venues on Street, Queens Road and Park Row.
The Sandwich Sandwich menu includes hearty sandwiches made to order.
