Burrito Mama, the new takeaway burrito restaurant from the founders of Wahaca, is due to open in London in October.
The takeaway concept occupy London's One New Change shopping centre, in the heart of St Paul's. A new, separate Wahaca site will be opening in the same development.
The takeaway restaurant will have its own 30-seater restaurant space.
Customers can order either from one of the Burrito Mama team or use self-service screens, and pay while their burrito is prepared.
There will also be an official Burrito Mama mobile app, allowing customers to order a burrito remotely and jump the queue.
Wahaca and Burrito Mama co-founder Thomasina Miers said: "We are 100% focused on better burritos, faster. Over the years, we have noticed that around 90% of customers order our burritos without making any bespoke tweaks, but we still go through the process of asking them every ingredient to put in, slowing things down. At Burrito Mama, we're taking all our knowledge of what people love, making it taste extra special and then using that as our recommended choice for customers."
