i want to say that i loved in-n-out, but unfortunately, the burger was good on an empty stomach, and the fries were mediocre. We asked for them well done, and they still seemed under-cooked. I can't see how people compare it to shake shack, as both have completely different styles. shake shack is more of a gourmet burger compared to in-n-out, but in-n-out is more reasonable priced for a burger. I don't think i would crave their burgers or fries, but i would have it if we happened to be near one and wanted a quick bite.
