In-N-Out Burger

Burger freaks from the East Coast make their holy pilgramage when in town for fun to this location of the storied franchise. What makes it so special? Could be their limited menu of five items: Double-Double (double cheeseburger), Cheeseburger, Hamburger, Fries, Shakes. Could be their "secret" menu of six more things (more or less: different ways of having the above items prepared). Could be their ingredients: always fresh, never frozen, pre-cooked, or inclusive of the usual garbage in fast food joints. Real ice-cream in the shakes. Real hand-shredded potatoes, fries cooked in-house. Real meat, burgers cooked to order. Could be their reluctance to expand past Arizona. Could be this location, where Vegas denizens of all stripes - pimps, low riders, thugs, suits, tourists, average locals, teens - come to congregate. Could be the 1 AM closing time. Whatever it is: it works, it's the best, it isn't to be missed. Multiple locations around Vegas.
