I am not sure if you can get this as an option to share but it definitely was not offered as an option for single.
However we did enjoy this meal, excellent food and great service.
We did lunch.
Just a note:
You cannot get sushi as an appetizer even if on the deluxe dining plan... you can however get it as the entree and if this is something you want, make sure you request the sushi menu so you can see all options including the combos.
