a goodcheeseburger, chocolate shake and fries; you can’t get a meal more american than that. there are two, what i’ll call, old-fashioned dive burger joints in livermore. there is ben’s burgers, which i wrote about back in june; and there is john’s char-burgers, which just happens to be #29 of my great livermore restaurant challenge adventure where i’m on my way to eat at every restaurant in livermore.
