Burgerville advertises its usage of antibiotic-free beef that comes from cattle raised in the Pacific Northwest.
The chain uses 100% real beef, delivered fresh every day, and never frozen in all of its simplistic menu items.
The chain's restaurants are spread across 26 states but are concentrated in Wisconsin, on the west shore of Lake Michigan.
The bulk of Whataburgers is located in Texas, but the chain's footprint already spans 14 states and will continue to expand in the coming years.
Cook Out got its start in 1989 and currently has a footprint of 313 stores spanning ten states.
Milo's Hamburgers got its start in 1946 in Birmingham, founded by Milo Carlton, a former U.S. Army mess cook.
