I wrote a detailed report about the F service on this flight from back in 2002.
Here is the the link:

It is toward the end of the report, so scroll down if you don't want to read the whole thing.
Bottom line, I would choose this flight over the night flights anytime. The service is great. As Carfield said, you get a full lunch service after takeoff and a dinner, which features an appetizer, a main course and a dessert. OF course, there is a separate menu for snacks. Even though it is a day flight, you'll get a duvet and the pajamas.
Take it, you won't regret it!
