RECOMMENDED: My car got sucked into the drive thru by the intergalactic tractor beam so I had to appease it by ordering a Double-Double and some well done fries!
In-N-Out is part of what makes the West Coast the West Coast. I love that they make their burgers fresh to order and only use fresh meat. The fries took a little to adjust to, since I had grown accustomed to the crap other burger joints put in their fries. Not In-N-Out... You can see them cutting up whole potatoes to make their fries.
In-N-Out is known for their "secret" menu. My advise is to ask someone in the know or simply read the comments on the listing here in Yelp for some hints and insight.
My personal favorites are the Double Double or the Triple Triple. Simply put... That's 2 patties with 2 slices of cheese or 3 patties with 3 slices of cheese! I order mine Animal style! Ask for this and you'll certainly never order it off the menu again.
The North Scottsdale location is easy to get to. It's always clean and the staff is impressive! It's hard to beat In-N-Out in the fast food burger niche. Enjoy ;-)
