Whataburger

On Aug. 8, 1950, an adventurous and determined entrepreneur named Harmon Dobson opened up the world’s first Whataburger on Ayers Street in Corpus Christi, Texas. He had a simple goal: to serve a burger so big it took two hands to hold and so good that after one bite customers would say, “What a burger!” He succeeded on both counts and turned that one little burger stand into a legend loved throughout Texas and the South. Today, each and every Whataburger is made to order, right when it’s ordered. And they’re still made with 100 percent pure, never-frozen beef and served on a big toasted five-inch bun with all “the extras” to suit your taste. Grilled jalapeños, extra bacon, three slices of cheese, no tomatoes, extra pickles? No problem. Your Whataburger will be made just like you like it, 24 hours a day, seven days a week. Whataburger’s following has grown exponentially in its more than 75-year history, thanks to a number of features, including its famous burgers and growing list of menu items, its iconic orange-and-white-striped restaurants and its famous Fancy Ketchup. Whataburger is more than a burger chain. It’s a place that feels like home to more than 51,000 employees, called Family Members, and millions of customers. It’s a brand built on pride, care and love. It’s a place people count on in their communities. It’s a place where goodness lives. So now with more than 1,100 Whataburger restaurants across 16 states stretching from Las Vegas to the Carolinas, road-trippers and hometown folks alike continue gathering under the big orange-and-white roofs for fresh, made-to-order burgers and friendly service.
