Russian consumers with open wallets are the magnet pulling multinational fast food chains to Russia. Wendy’s/Arby’s Group is the latest such chain to embrace the rubel-spending power of a growing Russian middle class. They have plans to open up to 180 restaurants in the next 10 years through a deal with Wenrus Restaurant Group, a subsidiary set up by Food Service Capital which operates the popular Goodman's Steak House chain among other brands. Yum Brands Inc has agreed to buy out Russian partner Rostik Group from the 161-outlet chain Rostik's-KFC, while PepsiCo, McDonald’s and Coca-Cola have all said they planned to keep investing in Russia.
