Sabatini's is amazing, but go hungry. You'll be there for at least 2 hours eating. I loved the Crown Grill, the Black and Blue onion soup is amazing. The extra fee does include gratuities, however, we left extra in both places. You do not have to. I normally do not do the extra fee restaurants, but had received the vouchers as gifts from a dear friend. Sabatini's was too much food for me, but it is wonderful and so is the Crown Grill. I had the best filet there. We had eaten at Ruth Chris before the cruise and I had ordered the filet there. The one we had at the Crown Grill put Ruth's to shame.
I hope you enjoy Princess as much as we do. They're my favorite line, so far. I can't wait to get back on board!
