Bar Louie, the self-described gastrobar that began in Chicago in 1990 and expanded across the country with more than 100 locations, has filed for Chapter 11 bankruptcy and closed multiple restaurants. In Colorado, at least three stores closed suddenly over the weekend — in Westminster, Colorado Springs and Fort Collins. In all, 38 Bar Louie locations closed recently across Colorado, Ohio, Wisconsin and Michigan, CNN reported Monday. “The company does not expect the (bankruptcy) filing to have meaningful impact on its day-to-day business,” Bar Louie management said a statement released Monday.
