How to know someone's exact location?

Someone I know shares their location with me (on the iPhone) but I would I be able to find out exactly where they are? Like not just show me a dot, I would like to be able to see they are at a mall, a certain restuarsnt, etc.

I'd not even bother with it. To be honest, that's kind of borderline unethical to even want to. Chances are, their phone doesn't display their exact location, so it might even be against the law to bypass that protection. Don't know.
