The 1,400 sq ft site will feature 65-covers, including a bar area with more casual seating.
Bánh Bánh was created by the Nguyen family with dishes inspired by their grandmother, who worked as a chef in Saigon in the 1940’s.
The siblings began Bánh Bánh as a London pop-up, before launching their first permanent location in their home borough of Peckham last year.
An Nguyen told BigHospitality last year that the family ran the restaurant as a tight-knit unit, with the two brothers in the kitchen and the three sisters front-of-house.
“There’s an honesty there that you don’t get from working with friends of colleagues,” said Nguyen. “That allows us to be more receptive and push each other to be the best.”
She added that though the siblings were keen to expand they were wanted to keep Bánh Bánh as a family business.
Property agency Shelley Sandzer acted for Bánh Bánh to secure the Brixton site.
“Brixton has become a key destination for top restaurant brands and we have no doubt that Banh Banh will also reap the rewards of this buzzing location,” said Shelley Sandzer’s Ben Freeman.
