I agree, and legally I'm sure it is 100% what is legally 100% beef in America. Cow nostrils hooves and eyeballs are also beef. When Checkers first opened they claimed only that their meat was 100% USDA Inspected. Good to know even if meaningless as you can't serve un-inspected meat. I still stop into Checkers now and then.Given the propensity for suing in today’s litigious society, if Whataburger publicly claims their hamburger patty’s are 100% beef, I believe it.
