A great late night easy dinner. In-N-Out's quality is consistent, with good fries and a quasi-secret menu. My favorite order is a cheeseburger, animal style, with extra chiles. Animal style just means grilled onions and thousand island dressing, but it definitely dresses up their plain burger. The various locations throughout the valley can get really crowded depending on what time you go, so that's worth considering.
The menu is small, but that keeps the prices low! It's cheaper to get a meal for my boyfriend and I here than at any of the other fast food places. The employees are also quite friendly.
There are small bible references on some of the packaging, like the cups and fry packages. I'm not sure what they reference, so if anyone knows that could be interesting to find out!
