Lasan owners Aktar Islam and Jabbar Khan are set to open a fourth site in Birmingham.
The pair, who are behind Lasan, Indian street food café Raja Monkey and Argentinian Fiesta Del Asado, have signed a deal to open a new restaurant at 130 Colmore Row, opposite Birmingham Town Hall, subject to planning permission.
Chef director Aktar Islam said: "It's important for us to continue investing in Birmingham. Both Jabbar and I were born and bred in the city, so when we're expanding it's key for us that we are reinvesting here. The location means it's one of the largest investments we've made, so it's an exciting time for us.
"We want to add value to the city's culinary scene, which is already world class, but what we intend to do here will push it a little bit further. We're known for taking cuisines and concepts and pushing the boundaries and we've got a proven record of doing it.
"For us, it's a great statement for the brand. We're an independent group born in Birmingham and it's great for us to put our mark on the city. It could be a big part of our lasting legacy."
Anthony McCourt, director at property development firm Court Collaboration, said: "This is a first rate building and would serve many uses well, so to get one of Birmingham's best-known culinary teams signed up as tenants proves the strength of the market here.
"Aktar and Jabbar have been at the vanguard of Birmingham's flourishing culinary scene as its reputation continues to grow and they've shown a versatility with their past venues that could bring something new to the table here.
"130 Colmore Row gives them a substantial canvas to serve up something brilliant."
