I'm old enough to have eaten burgers out of styro boxes, and IMHO it's not one of the things I get nostalgic over. They held heat *a little bit* longer than cardboard/paper, but that's basically the only advantage. The places here that offer kebab/fries and sausage/grilled whatever to go still use larger styro trays here, and they're less convenient and sturdy than the styro burgerware was. I'm actually hoping someone comes up with an alternative.
