Is the pu platter a real food?

There's no food called a "pu platter." It's likely a misunderstanding or a typo.

Could you please provide more context?

* Are you trying to find a specific dish? If so, could you describe what it's supposed to be?

* Did you see it on a menu or in a recipe? If so, could you share the source?

* Perhaps you meant something else entirely?
