Whataburger is incredibly good. A Whataburger is 1/4 lb, with a wider-than-average variety of fixings, made fresh to order. It is, as the sign states, open 24 hours, with a huge breakfast menu from 11p-11a. The menu overall is pretty diverse, including beef and chicken fajitas and chicken strips with white gravy. Sides and drinks can get pretty big, too. Being from NW Florida, I have to say it's my absolute favorite fast-food joint.
That, my good man, is a Texas institution. We love it as much as Californians brag on In-and-Out. We;re just quiet about it. It's our little secret.
They still properly grill the buttered-up buns w/ each fresh grilled patty. And they've got the best fixins' going. And the frys... forget about it! Oh- and shakes are still hand-dipped, breakfast it top-notch, and the chicken offerings aren't made from compressed pucks of mined "parts."
