Chi-Chi's is a single Mexican restaurant currently operating in Vienna, Austria, that is the only remnant left of a much larger chain.

[1] The company was briefly owned by Tumbleweed, Inc.[2][failed verification] The chain also once operated in the United States and Canada but exited those countries in 2004, and closed their German and Belgian locations in 2022.

The first restaurant opened at 7717 Nicollet Avenue South, in Richfield, Minnesota (a suburb of Minneapolis) in early August, 1976.

[10] The hepatitis was traced back to green onions at the Chi-Chi's at Beaver Valley Mall near Monaca, Pennsylvania, about 30 miles (48 km) northwest of Pittsburgh.

[22] The last snapshot of the European chain's official website in January 2022 showed that the company had three locations left, two in Liege and one in Brugge, all in Belgium.

[25] In 1987, Hormel Foods acquired the rights to produce and market Chi-Chi's branded salsa and related products in the United States.

In April 2021, MegaMex hired a TikTok personality to be their Chi-Chi's brand ambassador for that year's Cinco de Mayo advertising period.
