Chi-Chi’s was once one of the most popular Mexican restaurant chains in America. With its festive atmosphere and Tex-Mex fare, it became a go-to spot for casual dining starting in the 1970s. But if you haven’t seen a Chi-Chi’s in years, there’s a reason – the company went bankrupt in 2003.

If you’re short on time, here’s a quick answer to your question: Chi-Chi’s grew rapidly through the 1970s-1990s but was hit hard by a hepatitis A outbreak traced back to green onions at one of its restaurants in 2003. The bad publicity led Chi-Chi’s to file for bankruptcy later that year.

This article will explore the origins and growth of Chi-Chi’s, discuss the hepatitis A outbreak and its fallout, and explain the ultimate demise of the once-popular chain.

The Origins and Early Success of Chi-Chi’s

Chi-Chi’s, the popular Mexican restaurant chain, was founded in 1975 in Minneapolis. It was the brainchild of entrepreneur Marno McDermott, who wanted to bring authentic Mexican flavors to American diners.

McDermott, a lover of Mexican cuisine, saw an opportunity to introduce a new dining experience that combined delicious food with a vibrant and festive atmosphere.

With its unique concept and menu, Chi-Chi’s quickly gained popularity in Minneapolis and became a local favorite. The restaurant offered a wide variety of Mexican dishes, from sizzling fajitas to cheesy enchiladas, all made with fresh ingredients and bold flavors.

The vibrant decor, featuring colorful sombreros and festive murals, added to the overall dining experience.

Word of mouth spread, and soon Chi-Chi’s reputation grew beyond Minneapolis. People from neighboring cities and states flocked to the restaurant to indulge in its delicious Mexican fare. The success of the first location led to the opening of more Chi-Chi’s restaurants across the country.

The chain expanded quickly through the 1980s and 90s

During the 1980s and 90s, Chi-Chi’s experienced a period of rapid expansion. The chain capitalized on the growing popularity of Mexican cuisine in the United States and opened new locations in various states.

The restaurant’s unique combination of flavorful dishes, energetic ambiance, and affordable prices resonated with diners, making it a go-to destination for families, friends, and couples looking for a fun and delicious dining experience.

Chi-Chi’s continued to innovate and adapt to the changing tastes and preferences of its customers. The menu expanded to include vegetarian and gluten-free options, catering to a wider range of dietary needs.

The restaurant also introduced happy hour specials and promotions to attract new customers and keep loyal ones coming back for more.

As the chain grew, Chi-Chi’s became a household name in the Mexican dining scene. It was known for its lively atmosphere, friendly staff, and mouthwatering dishes. Families would gather at Chi-Chi’s to celebrate birthdays, anniversaries, and other special occasions, creating lasting memories over plates of sizzling fajitas and bottomless bowls of chips and salsa.

The Hepatitis A Outbreak That Changed Everything

In 2003, a Chi-Chi’s restaurant caused a major hepatitis A outbreak

Chi-Chi’s, once a popular Mexican chain, faced a significant setback in 2003 when one of its restaurants became the epicenter of a hepatitis A outbreak. The outbreak, which originated from contaminated green onions, affected hundreds of people who had dined at the restaurant.

This incident not only tarnished the reputation of Chi-Chi’s but also had far-reaching consequences for the entire chain.

The outbreak caused widespread illness and several deaths

The hepatitis A outbreak caused by Chi-Chi’s restaurant had devastating consequences, leading to widespread illness and tragically, several deaths. The contaminated green onions served at the restaurant were traced back to a supplier in Mexico, highlighting the importance of stringent food safety regulations and quality control measures.

The severity of the outbreak sent shockwaves through the food industry and prompted a reevaluation of safety protocols.

Chi-Chi’s faced backlash and plummeting sales

Following the hepatitis A outbreak, Chi-Chi’s faced significant backlash from the public and a sharp decline in sales. Customers were understandably wary of dining at the chain, fearing another outbreak.

The negative publicity surrounding the incident, coupled with the loss of consumer trust, proved to be a fatal blow for Chi-Chi’s. Despite efforts to regain customer confidence, such as implementing stricter food safety protocols, the chain was unable to recover from the financial and reputational damage.

The Downfall and Bankruptcy of Chi-Chi’s

Negative publicity from the outbreak continued to hurt the chain

Chi-Chi’s, once a popular Mexican restaurant chain known for its festive atmosphere and delicious cuisine, faced a major setback in 2003. The chain was hit with a devastating foodborne illness outbreak that originated from one of its locations.

The outbreak, caused by contaminated green onions, resulted in the deaths of four people and sickened hundreds more. This incident received widespread media attention and created a significant blow to Chi-Chi’s reputation.

The negative publicity surrounding the outbreak led to a sharp decline in customer trust and an overall decrease in sales. Despite efforts to contain the situation and reassure the public of their commitment to food safety, Chi-Chi’s struggled to regain its former standing in the restaurant industry.

The timing of the outbreak was particularly detrimental, as it occurred during a time when consumers were becoming increasingly concerned about food safety. This heightened awareness, combined with the media coverage of the Chi-Chi’s incident, made it incredibly challenging for the chain to recover.

Chi-Chi’s filed for bankruptcy in 2003 and closed most locations

Unable to overcome the financial and reputational damage caused by the outbreak, Chi-Chi’s was forced to file for bankruptcy in 2003. This decision was made in an effort to restructure the company and reduce its debts.

As part of the bankruptcy proceedings, Chi-Chi’s closed the majority of its locations across the United States.

The closure of these restaurants not only resulted in the loss of jobs for many employees but also left a void in the dining options for loyal Chi-Chi’s customers. The once-thriving chain was now a mere shadow of its former self.

Despite the closure of most locations, a few Chi-Chi’s restaurants managed to survive. These remaining establishments were either independently owned or located outside of the United States. However, even these surviving locations faced an uphill battle in rebuilding customer trust and reviving the brand.

The company ultimately liquidated in 2004

Despite its efforts to bounce back, Chi-Chi’s was unable to reverse its declining fortunes. The chain continued to struggle with low sales and mounting debts, ultimately leading to its liquidation in 2004.

Chi-Chi’s bankruptcy and subsequent liquidation marked the end of an era for the once-beloved restaurant chain. It serves as a cautionary tale about the importance of food safety and the devastating consequences that can arise from a single, highly publicized incident.

While Chi-Chi’s may no longer be a presence in the restaurant industry, its legacy serves as a reminder of the importance of maintaining the highest standards of food safety and customer satisfaction.


Chi-Chi’s was once a staple of American casual dining, with its fun atmosphere and tasty Tex-Mex dishes attracting hordes of patrons. However, the hepatitis A outbreak traced back to one of its restaurants ended up being a death blow for the company.

Though Chi-Chi’s tried to recover from the bad publicity, the damage was done, and the chain was never able to regain its footing. After declaring bankruptcy in 2003, Chi-Chi’s shuttered almost all of its restaurants over the next year, signaling the end of an era.

Though long gone, Chi-Chi’s lives on in the memories of those who enjoyed its hot, hearty fare in its heyday.
