About one week after e-mailing both the hotel and the general manager, the food and beverage manager sent me an e-mail. He did not want to discuss the e-mail that I sent but he reference the post on this site as the cause for why he wanted to have a chat. After responding to his e-mail saying I am happy to chat, and I was happy to be alive after I was food poisoned, no further contact was made.
The second part of this two part posting, including the e-mail that was sent to the Melbourne Marriott, including the General Manager, can be found here.

After making edits to this post and republishing it on 14/09/12, I refreshed the statistics from Urbanspoon and found that 71% of the (28) reviewers on that site liked Essence Restaurant. Perhaps the typical standard hotel food is just fine but I would suggest steering clear of the seafood!
