I always get the carbonara, usually with the filet but you'll tell us.
In the past I've also asked for the fried calamari from the the lunch menu as an app and it hasn't been a problem (much better than what you posted from Fish N Ships no doubt).
Cannolis sometimes wind up as a to-go dessert after all that.
Giovanni's has always been the one specialty restaurant we pay for when it's available. As a frugal cruiser, we used to always eat there on night one when RC had the "first night done right" BOGO promo.
