Rosinter Restaurants, Russia's largest casual restaurant chain, is to raise $25m via a share placing. The country's only listed restaurant group said it would use the funds to pay down debt and to develop the business for the future. Rosinter has a $72.5m debt pile but suffered last year as Russian consumers tightened their belts, leading to a slight 0.7% sales increase and a 16.1% like-for-like sales fall. Rosinter owns chains such as Planet Sushi and operates the franchise of TGI Friday's. The company also has a joint venture with Whitbread to develop the Costa Coffee brand in Moscow.
