Chi-Chi's was a popular Mexican restaurant chain from 1975 to 2004. It ceased to exist within the United States following a 2003 Hepatitis A outbreak that began at one of its locations in suburban Pittsburgh, Pennsylvania. Chi-Chi's is still in operation in Belgium, Luxembourg, United Arab Emirates, Kuwait and Indonesia. Chi-Chi's also operated in Canada. A division of Chi-Chi's operates under the name Tumbleweed Restaurants in Kentucky, Indiana, and Ohio.[1][2] Chi-Chi's also marketed a line of grocery foods (later purchased by Hormel) with an emphasis on salsa.
