There may have been at one point, but there is no Whataburger in the DFW airport. There is a Fuddruckers, Chilli's Too, TGIFridays, Gas Monkey, McDonald's, Salt Lick, Wendy's, I.H.O.P., Wing Stop, and now Garrett's Popcorn and Chic-fil-a, among many excellent additional options. Many even have mobile ordering for short layovers!
Yes there are actually several.
