I read the question. OP seems to be asking where to get the best burger. Presumably, they are asking about chains because they want something available nationwide. But, as stated:
Most chains aren’t nationwide.
Most chains aren’t the best place to get burgers.
Now, I’m all for narrow-minded pedantry, and there’s a time for answering a poorly-phrased question literally; but I was actually trying to be helpful, here, by reading critically and giving OP a useful answer to the question: “When visiting the US, where should I go for the best cheeseburger?”

You didn’t even answer your own question, which also isn’t what OP asked or meant.
No idea how you’re being useful there.
