Frisch's

Frisch's Big Boy is a regional Big Boy restaurant chain with headquarters in Cincinnati, Ohio. For many years a Big Boy franchisee, in 2001, Frisch's became the exclusive owner of the Big Boy trademark in Indiana, Kentucky, and most of Ohio and Tennessee, and is no longer affiliated with Big Boy Restaurant Group. In July 2022, there were 84 restaurants in Indiana, Kentucky, and Ohio. This included 11 Big Boy stores in Cincinnati, 6 in Dayton, Ohio, and 3 in Louisville, Kentucky. Frisch's is the oldest, longest surviving, and largest regional Big Boy operator, excluding Bob's Big Boy in California, which was the original Big Boy restaurant and franchiser. (However, Frisch's is significantly larger than the original Big Boy chain, which makes up Elias Brothers, the Bismarck Big Boy, and Bob's.) As of April 2024, the company operates 87 locations in Indiana, Kentucky, and Ohio. The last new Frisch's opened in Dry Ridge Kentucky in 2019, therefore 8 stores reopening from COVID-19 around 2022-2023. Many stores closed afterwards, likely due to rising supply chain costs and restaurant demand changes, as well as shifting customer demand away from "diner" restaurants.

Leadership of Frisch's passed from founder David Frisch to his son-in-law and finally his grandson, until 2015, when the company was sold to Atlanta-based NRD Capital, an equity fund which focuses on restaurant development. Frisch's also previously owned numerous Golden Corral restaurants in Indiana, Kentucky, Ohio, Pennsylvania, and West Virginia but after closing six under-performing stores in 2011, Frisch's sold the remainder in March 2012.
