March 2017: Open, full brekkie in lounge, along with afternoon tea service, and "evening delights" (warm and cold snacks), and other offerings.
Unlike 9/16 Update, I did not receive option to take breakfast in hotel restaurant.
There's an extensive array of benefits for Platinum guests as shown in the attached image, as well as other details on lounge policies. Sorry that the photo isn't the greatest. The welcome letter is printed in silver paper (or maybe it's platinum paper
).
