What Happened to Mama Rita's After Kitchen Nightmares? (Newbury Park, CA)

Mama Rita's Mexican Cantina was a Newbury Park, California restaurant opened in 2008 by Laura Papenfus, who had previously run a successful catering business, according to Dexerto's 2023 account of the episode. Papenfus stated in a comment posted to a later fan site update that she opened the restaurant in a nearly empty shopping center during the 2008 recession and that it took three years to build the business up to that point. By the time of Gordon Ramsay's 2009 visit, the restaurant was an estimated $2.2 million in debt, and Ramsay found the kitchen relying heavily on frozen, pre-cooked food; Reality TV Updates describes roughly $12,000 worth of frozen product in the restaurant's freezers, some of it nearly a year old, along with reports from past customers of food-poisoning symptoms after eating there.

Ramsay brought in chef Naris Mardirosian as a temporary head chef to help retrain the kitchen around fresh ingredients, and the relaunch, while rocky in its first stretch of service, ultimately went well according to the recap. Papenfus stated in the same fan-site comment that much of the show's more sympathetic footage of the family was cut for time, and that she and her staff had asked for the show's help mainly for publicity. After the show, Papenfus kept original chef Perla in the head chef role rather than following through on the planned staffing change, and largely reverted to the restaurant's prior menu.

According to Dexerto, Mama Rita's closure came in December 2010, several months after the episode aired; Reality TV Updates independently corroborates a December 2010 closing date and reports that customer reviews had stayed fairly positive up to that point, pointing to the restaurant's debt load as the more likely cause. Papenfus later worked at Mission Oaks Cafe in Camarillo, California, a restaurant she says in her own comment on a fan-site update that she helped rather than owned, which itself shut down in 2019. As of the most recent fan-site updates, the Newbury Park space that had housed Mama Rita's was occupied afterward by a restaurant called The Local Table and, according to a 2024 update citing the Conejo Valley Guide, more recently by a restaurant called Gema.
