Do you know implies you have personal experience of a/the restaurant; Do you know of is looser, asking if you know whether there is a good restaurant.

Thank you. Is this common English?

Here is anonther example,

Do you know of what is this?

How this differ from Do you know what is this?

I'm just trying to figure this out.

"Do you know what this is?"
"Do you know what is this?"

Both sentences share the same meaning. Also, you can say.
" What is this?"

The statement "This is a rock." and the question "Is this a rock?" cause the examples you see. "what this is" is used more, but I say both are correct.
