I grew up on White Castle hamburgers. I remember my Dad driving us into St. Louis to get a bag of burgers. Nothing better than a half dozen or so burgers with horseradish mustard. We don't have them in Texas, but since my last trip they opened one in Las Vegas. It was a must to stop there. I would have brought some back on the plane but I didn't want everyone asking what the smell was, because the smell is so good.
