I am not usually a fast food person, but I’ve tried In n Out several times, because it seems to be recommended, in the last couple years due to travel taking me to their territory and haven’t found it to be particularly good. Compared to McDonalds, which I also rarely frequent unless it’s a splurge day from the gym or I’m on a road trip, it seems objectively worse. The McDonalds quarter pounder and double quarter pounder are significantly better than InO.

My suspicion is, like Whataburger, it’s a bit of a “having grown up with it” sort of thing that makes people recommend it so highly.
