I think maybe my first visit ever to In-N-Out at the corner of I-15 and Paradise in Vegas must have permanently tainted my view of the cleanliness factor of that place. Disgustingly dirty. Just grimy, sticky tables. Bathroom in shambles. Since then, I've been to several throughout Utah and a few in California and I've usually been unimpressed with the cleanliness factor. Mostly just tables that need to be wiped down. The food was good for the price I paid, but I wouldn't compare In-N-Out with Chick-fil-a for cleanliness.
