We have that here. No comparison, especially the french fries. In-N-Out has the best fries, period!!
Wish they would come to the mid-west. Maybe testing out the Dallas market will bring them a little further north.
When I started with McDonald's, most of our stores were still doing fresh fries.
It was an incredible amount of work and quality varied greatly. I'm sure In-N-Out has access to much better and consistent potatoes than we did 40 years ago, but it still takes a huge effort. I'm amazed that they are so consistently good!
