I made some changes/updates to a reservation for march and in the confirmation email it states:

Renovation is in progress on limited guest floors. Noise can be expected between 10:00 AM and 5:30 PM Mondays to Fridays and intermittent noise may occur during weekends and public holidays. Grand Cafe is scheduled to undergo renovation starting 1 October 2015 until May 2016, the same month the entire guestroom renovation will be completed. During this period, guests will be informed of the alternative breakfast venue upon check in. Other restaurants and bars, Plateau Spa, the fitness studios and business center will maintain normal operations.

Since Diamonds are offered the option of taking the breakfast buffet in the grand cafe in addition to the lounge, with the Grand Cafe, where will breakfast be offered?

From the Grand Cafe Website:
Grand Cafe is currently closed for renovation until May 2016. During this period, Tiffin will be open all day from Breakfast at 6:30am till midnight and Grand Hyatt Steakhouse from 12 noon till midnight. Other restaurants and bars will maintain normal operations.

My assumption is that Diamonds would be offered Breakfast buffet if they wish to take that option in Tiffin. Can anyone Confirm this and how was the experience?

Thanks!
