If I change "that's dying" to "that's being" or "it's", does the meaning get changed?

It would not make sense to say "that's being" in this case because the main verb here is "dying". So if you say "that's being" instead of "that's dying" then the verb "dying" would not be there. It would also not make sense to say "it's dying" here because he is referring specifically to the restaurant that is in this situation. So "that is dying" is the only way that makes sense grammatically here.
