I go there because they’re there. Good or bad still depends on the owners and management. Many times, good is enough. Good is what makes all those other places exceptional. Chain restaurants even serve a divine purpose: seriously, if we got rid of Little Caesar’s; church youth groups would be decimated.
Didn’t see a mention of In and Out Burgers but they are highly regarded in the areas they serve (Southern CA is my area). Fresh meat for the burgers (not frozen); ditto for French fries, and a simple menu that ensures fast service despite noon-time mobs.
