Gourmet Burger Kitchen (GBK) branded burgers are to be sold in supermarkets for the first time later this month. Clapham House Group, the restaurant operator behind the global brand, said that Waitrose and Ocado, the online retailer, would soon stock its range of burger patties. In a statement released this morning, to tie in with the unveiling of its preliminary results, Clapham said: “We believe that this initiative could develop into a potential new profit stream for the GBK brand and also provide us with a route to communicate our brand and values to a much larger audience.” It added: “Over recent years there has been an increase in demand in supermarkets for fresh beef burger patties. We are also aware that consumers are eager to recreate restaurant experiences at home and want to be reassured by quality brands. “To date the UK retail burger market currently has had no nationwide fresh restaurant branded product presence. We are delighted to announce the launch of the GBK 100% fresh Aberdeen Angus Pattie. This will go on sale in more than 60 Waitrose stores and Ocado from July 2010.” Nando’s, Pizza Express and Wagamama also have branded products for sale in retail outlets.
