"What do you think is this pizza any good? "
Is this sentence correct?

Why did you post it in this thread? I see no connection. You could have started a new thread.

That should be two sentences.
What do you think? Is this pizza any good?

“What do you think is the difference between mega-size drink and mega-sized drink?”
is coming in #1 post.
If this is grammatically correct, then “What do you think is this pizza any good?” must be correct?
Am I wrong?

You are wrong.
…the difference between a and b…
is not the same pattern as
What do you think (about something)

Once again, I would point out that it is not a good idea to guess at the meaning of a sentence based purely on a perceived pattern in the grammar. The setting/context of the sentence often changes the purpose of the pattern.

Just because the words in a phrase are identical and the word order is the same, this does not mean that the purpose/pattern is identical too.

Hi,
My guess is being grounded on the Merriam-Webster’s explanation of ‘king-size’ (‘king-sized’ as a synonym)–‘unusually large’.
