Fun little story in the Dallas Observer: Reporter takes three Dallas burger kings (from The Grape, Maple and Motor and Angry Dog) and asks them to review the In-and-Out Double versus a standard Whataburger. They seemed to lean towards the Whataburger. I've had both and I think I prefer the In-and-Out, but I've only had one In-and-Out versus dozens of Whataburgers...I think I'm just not a fan of mustard on my burgers. I guess I could just ask them to leave it off.
Anyways, the link is below if you want to read. Otherwise, share your thoughts on Dallas burgers, In-and-Out, FMK, dinopenis, movie criticism, the true start of the Romantic period in literature or whatever else strikes your fancy.
