The whole point of a minimum wage increase is that it will increase all restaurants' wage costs to the same degree, at the same time. Meaning that going "down the street", potential diner's will find that all restaurants' prices have increased equally. So the business threat isn't that American consumers will abandon "Dale's" in particular for some other restaurant. It's that they will choose to eat at home instead of eating at a restaurant, or that they will order less food when they do go to one.
