I have been on three carnival cruises:
My favorite entree was the Sea Food Platter (which was seen in a photo in one of the previous replies in this post). It included Florida Lobster tail and shrimp. The NY Strip Steak was a close second.
My favorite soup was Chilled Sweetened Mango Soup.
My favorite dessert was (like everyone else) the Chocolate Melting Cake.
I also enjoyed the Pizza in the aft Lido area.
I enjoyed the sushi they had at the sushi bar.
I also enjoyed quite a few cheeseburgers and hotdogs at the grill in the aft Lido deck area (across from the Pizzeria).
