Whataburger founder Harmon Dobson's goal was to create a burger so big that customers would have to use both hands to hold it. It would be so good that at first bite they would declare, “What a burger!” Thus, in 1950, Whataburger was born.

What started off as a burger stand, almost 70 years ago, now has 700 restaurants in the US. Although it lost out to In-N-Out Burger in Business Insider's taste comparison, it's still a favorite of many in the south.
