Yeah. Don't get me wrong.  I like In-n-Out.  I think their standards are high on quality, and the way they train and treat their people, which translates into a good customer experience.  I would go there every couple of weeks when I lived there.  And I will usually stop in when I go for a visit.  But I don't think it's the holy grail like some seem to. 

Living in the Bay Area you kinda get spoiled with great food choices.  My go to for a great burger when I lived there was the Counter.  I could get a great burger of beef or bison, (or even tuna) with my choice of fresh add-ons from a nearly endless list. Along with an ice cold IPA to go with it. :-)
