Buenos Aires Restaurants, the steakhouse chain, hopes to open two further sites this year in the South East.
The group, which was founded in 2007 by Cristian and Linda Barrionuevo, has already secured the Octopvs bar site in Horsham, West Sussex, for an opening later this summer.
It is thought that the company is also in talks to secure a unit in Richmond for an opening later in the year.
It recently opened on the site of the Westerly bistro in Reigate.
The group also operates restaurants in the City, Chiswick, Croydon, Fulham, Maidstone, Purley and Wimbledon.
