I love that In N Out cooks everything to order. You can watch them prepare everything through the large kitchen windows as you go through the drive-thru. I love watching them put the potato in the slicing instrument and watching the fries come out the bottom, get put in a bowl and then get put in the fryer. Nothing frozen here. And you can taste the difference.
Insider tip: You can get fresh grilled onions on your burger if you want!
