The restaurant, located on Great Castle Street, will serve 60 covers across two floors and be the group’s largest to date.
It will continue to serve the same Mexican street food featuring freshly-made burritos, tacos, salads, soups and other seasonal Mexican dishes as its other locations on Goodge Street and Covent Garden.
Cocktails, predominantly Tequila-based drinks, will be key to the site’s offer.
Ben Fordham, founder of Benito’s Hat who opened his first site in 2008, said: “When we first opened with Goodge Street we really were pioneering the Mexican food movement in London. Three years on and the scene is now very much more established with demand for great tasting, authentic Mexican food on the rise.”
Executive chef Felipe Fuentes Cruz will continue to oversee the kitchens of all three sites.
Benito's Hat's expansion comes amongst a flurry of fast-casual Mexican restaurants rapidly expanding in London, including the five-strong Tortilla and Chilango, which has placed offers for its sixth and seventh sites.
