Hi, I have several menu's from the Century and Zenith from a year or two ago. I have been on Celebrity five times and the menu's have been similar. I can fax them from work tomorrow if you want them.
Cruise to the home page and read "Dinner at Eight -- for Two" That will at least give you a flavor the the menu in the specialty dining room which is NOT to be misssed !!
I've got several samples from a few years ago, but not a lot has changed. These were from the Mercury in 98. Go to http://www.jeffs.net/menu-frames.htm
If you go to www.mytravelco.com and click on cruises, then on a specific ship and there are many of them, there is a section about dining. You can check a sample menu and the wine list too.
