Big Boy restaurants are getting a big expansion! The new owner of the Frisch's Restaurants chain has big plans for the future of the franchise, including an expanded menu and new restaurants, according to the Associated Press.

NRD Capital Partners became the majority shareholder of the restaurant chain last week, a move that cost $175 million, according to the AP. Even though the company is now under private management, it will still keep ties with its founding family.

With 121 restaurants already in Ohio, Kentucky and Indiana, the Big Boy franchise will begin expanding into Tennessee, according to Fortune. The new management team is also considering opening restaurants in nontraditional locations such as college campuses, and will be adding new menu items to appeal to a younger audience.

But even with these changes in the works, Big Boy is still sticking to its roots. The restaurant will continue serving its signature Big Boy hamburgers with tartar sauce and hot fudge cakes, and is reviewing its contract with Pepsi, according to USA Today.

The plans for Big Boy's future are aimed at improving the brand, not necessarily changing it.

"We have tremendous respect for our customers' loyalty and we want to make the Frisch's brand even better for them," said Aziz Hashim, founder of NRD Capital Partners, reported USA Today.

"Our primary goal is to make sure our existing customer is totally taken care of. So, no plan to alienate our current customer base; we want to actually make it better for them. At the same time, we want to make an effort to drive some new customers," he added, according to the AP.
