Sochi is timely, but it isn't the only foreign city to have Pittsburgh restaurants. South Korea has a pair in Gyeonggi province: a bar in Siheung (경기 시흥시 은행로144번길 21-1) and a pizza place (경기 안산시 상록구 초당2길 14) in Ansan. They appear here courtesy of Daum's Road View:
There is also a hamburger restaurant with locations in Seoul and Boryeong called 더피츠버거, which is how "The Pittsburgher" would be romanized but is written PizBurger, a portmanteau of two primary menu items.
