Will,
If you remember the layout of the Statendam, the Pinnacle Grill is found in the area between the Explorer's Lounge and the Rotterdam Dining Room - they removed the King's Room, Maitre D's office, etc. and added the Grill.
I had the pleasure of dining in Ryndam's Pinnacle Grill (added to that ship about the same time as on Statendam). It was outstanding - a true, culinary delight and worth every penny of the $15.00 - and MORE. The Pinnacle Grill has its own high level of provisions and its own galley.
It will be added to the remaining two sisterships, Veendam and Maasdam.
Zuiderdam's Odyssey restaurant has the same menu (and charge) as the Pinnacle Grill.
