In N Out is good, but I don't know that they really deserve the cult following that they have, to be honest. Whataburger is something more local to you Texas weirdos more than anything else. Five guys is great... I've only had them a few times for whatever reason, but each time my mouth has been very happy. Being from Wisconsin, I also have to plug Culvers. Sweet, greasy burgers...

And just to put this out there for something totally different, I feel like I have to say *something* about White Castle. Terrible, terrible sliders that I have to get when I go home to MSP. Especially with certain... legalizations... in Colorado, I'm amazed they don't have any around here. You could make a killing opening one up on Colfax! If I were a businessman, I would absolutely do that. If you want to be really crazy, go during breakfast hours (they start at midnight, too). A slider with an egg on it. Trust me, they use actual egg and it's pretty darned tasty.
