The number of U.S. restaurants has fluctuated over the years. As of 1993, the U.S. chain had 30 restaurants in the United States and nine in Japan. In 2003, the U.S. company alone had 45 restaurants, in 14 states and Japan. The number of U.S. locations currently stands at 43, in Arizona, California, Colorado, Hawaii, Indiana, Kentucky, Minnesota, Missouri, Ohio, Oregon, Tennessee, Utah and Washington. The Old Spaghetti Factory (OSF) Japan locations were in Nagoya (closed 2013), Kobe and Kawagoe, Saitama (closed 2009). The downtown Seattle location, which opened in 1970 and was the second in the chain's history, was closed in December 2016, due to the sale of the building.
