Cosi was founded in Deerfield, Massachusetts, in 1996. The company operates a chain of restaurants that focuses on using flatbreads baked on site.
In 1999, the company merged for a while with restaurant/bar XandO, and a few locations were named Xando or Xando Cosi. The company sold the rights to its Washington, DC, stores to Capital C Restaurants, who operate them as franchises. Cosi has approximately 71 locations in the US and franchises in United Arab Emirates and Costa Rica.
Cosi filed for bankruptcy in September of 2016, forcing them to close approximately 29 of their company owned locations. The company is currently looking for a buyer.
