Why are In-N-Out cheeseburgers so good?
In-N-Out cheeseburgers are seen as good for a few reasons.  The meat is never frozen and tight quality controls at their processing plants insure a consistent and high quality meat patty.  The incentive structure for the In-n-out employee results in workers staying at the fast food chain longer with the manager frequently in charge of employees and the actual cooking of the burger patties.  This method is opposite of competing fast food restaurants who assign the burger cooking to entry level employees and customer management to higher levels.  In-n-out maintains a smaller menu focusing on a few key items instead of an expansive or seasonally themed menu making it easier to maintain high standards of quality.  Lastly their slow growth and enthusiastic fans provide a positive atmosphere lending itself to people thinking more highly of In-n-out where without this influence might be neutral on the brand.
