I'm currently aboard the Joy.
Platinum dinners changed to the following:
Top voucher:
Good for Cagney, Le Bistro, and ocean blue
Ocean blue is a new choice!
Bottom voucher:
Used to be La Cuchina and Food republic (because no Moderno on Joy).
Note: Food republic is limited to 4 dishes (no change)
Now the bottom voucher is good for all other specialty restaurants not listed in the above voucher.
That includes Tepanaki!
