The Subway restaurant chain has opened its first location in Bulgaria. The restaurant is owned and operated by Bulgarian native and resident Dimitar Serafimov and his friend and business partner Liudmil Stankov. Serafimov, a former attorney, spent six and a half years in Canada, where he became acquainted with the submarine sandwich concept. Stankov, a restaurateur in the Bulgarian capitol of Sofia, comes to the partnership with more than ten years of experience.
