The sandwich shop only has 199 restaurants in China now, but expects to have more than 500 by 2015.
Subway has achieved its rapid growth, in part, by opening outlets in non-traditional locations such as an automobile showroom in California, an appliance store in Brazil, a ferry terminal in Seattle, a riverboat in Germany, a zoo in Taiwan, a Goodwill store in South Carolina, a high school in Detroit and a church in Buffalo, New York.
"We're continually looking at just about any opportunity for someone to buy a sandwich, wherever that might be. The closer we can get to the customer, the better," Mr. Fertman says, explaining that it now has almost 8,000 Subways in unusual locations. "The non-traditional is becoming traditional."
The company has some concerns about the economies of certain international markets, such as Germany and the United Kingdom.
The company is trying to develop more affordable offerings in those countries, similar to the $5 foot-long sandwiches that have been successful in the U.S.
"Finding that kind of value proposition in those countries is essential," Mr. Fertman says.
