In-n-Out Burger

I have to admit, I am a huge fan of In-n-Out. It wasn't until I moved to Las Vegas that I had the privilege of eating there, and I am proud to say I am hooked. Apparently, there is a "secret menu" that if you know about, allows you to order your food with some interesting modifications. For example, an "animal style" burger (pictured below) gets you a mustard-cooked beef patty, additional pickles, extra secret sauce with grilled onions. Here is a link to the "secret menu" if you think you can handle it.
