I found a sample menu on Carnival.com for the Captain's Welcome Dinner that you can print out for your Husband. You will need Adobe Acrobat, but most computers have it, or a built in pdf reader.
On the menu, I reccomend the Pumpkin Soup and Mississipi Delta Prawns "I call them big shrimp" for the starters, and if he loves shrimp he can order 2.
On this night will be the Lobster and Prime Rib also. I usually order both, but can't eat 2 potatos so I ask to leave one off. They come as entrees on seperate plates. If you have a really good waiter they will know what you are doing and put the Lobster on the other plate for you once they bring it to the table. If you have a "super waiter" they will even take out of the shell for you.
Just trying to redeem myself from the earlier miss-assumption. Here is the link.
When Acrobat or whatever reader you have opens there will a print button..here I go assuming you might not know this
Best to you and husband,
