Buenos Aires Restaurants, the steakhouse chain, has secured a new flagship site in the City of London. The group, which was founded in 2007 by Cristian and Linda Barrionuevo, has secured the former Calico Bar & Restaurant unit, owned by Marston’s, in Watling Street, for its flagship London restaurant and bar. The 7,702sq ft unit has been taken at a rent of £202,500 per annum. The site, which will open later this summer, will become the sixth for the group that also operates restaurants in Croydon, Fulham, Maidstone, Purley and Wimbledon. Ross Kirton, director at Colliers International, which the let the property on behalf of Marston’s, said: “The taking of this unit by Buenos Aires is a testament to the growing demand for premium steak restaurants in the UK. Despite entering into a double-dip recession, this type of premium restaurant is still as popular as ever, and this really is a fantastic time for Buenos Aires’s first venture into the City.”
