One of the things I love to do while at home (in Texas) is to eat. Texas has its own style when it comes to food. Especially burgers. Being a Texan, I'm very picky about my beef. And I'm extremely picky about my burgers.
I don't always eat fast food burgers, but when I do, Whataburger is my poison of choice while in Texas. Whataburger is a homegrown company. The burgers come to you nice and hot. And it does take two hands to hold it.
This is one fast food chain I would highly recommend trying while in Texas. You can get your burger any way you want. Come early, around dinner time there is a long line at the drive through!
