FAT Brands has announced the development of 10 new co-branded Fatburger and Buffalo’s Express restaurants across several states in the US.

To be opened in California, Arizona, Texas, Pennsylvania and Virginia, the restaurants are scheduled to open this year.

Established by Lovie Yancey around 70 years ago, Fatburger serves made-to-order burgers, milkshakes, fries and chips. Its sister brand Buffalo’s Express complements Fatburger’s menu with fresh, boneless and bone-in chicken Wings with more than 13 sauce options.

“We are eager to serve our signature, all-American offerings to consumers within these markets and expand the national reach of both brands.”

The new locations in Monrovia, Bakersfield, Cerritos, and Lake Balboa will increase the brand’s presence across Southern California.

FAT Brands CEO Andy Wiederhorn said: “It is very exciting to see the expansion of Fatburger & Buffalo’s Express across the country.

“We are eager to serve our signature, all-American offerings to consumers within these markets and expand the national reach of both brands.”

FAT Brands currently owns Fatburger, Buffalo’s Cafe, Buffalo’s Express, Hurricane Grill & Wings, Yalla Mediterranean and Ponderosa and Bonanza Steakhouses. It currently has more than 300 restaurants, with around 300 more under development in 32 countries.

Buffalo’s Express was founded in 2012 in Los Angeles, California. It has co-branded with 72 Fatburger restaurants to date.
