In-n-Out has been in Nevada for at least 7 years now... probably longer, but thats when I started going there . We _FINALLY_ have a few in the Phoenix area (one not 10 mins from my house). Nothing beats a double-double animal style... and the fries are second to none.

Jack-in-the-Box is good, and by far the most prevalent fast food burger joint in this area (I have 3 in a 3sq mi area of my house). I like the bacon ultimate cheeseburger. For some reason I only end up ordering it after being at the bar all night though...
