I tried when when I was on the Grand in '19. The suite breakfast was in the CG and my request was denied. I didn't ask for lobster but the waiter said that they didn't have any crab. It doesn't hurt to ask and I will try again Sept 24 for 3 nights, YVR to SF.
On the plus side, our waiter brought me bottomless Bloody Marys and Mimosas, had them waiting when we arrived every morning. No charges to the folio. No drink plan.
