Although
Carfield did not include a menu, he used the Pre-Flight Dining on his trip back in June
(trip report here) before ZRH-HKG and said the quality of food was excellent. From the photos, it seems that it is a proper restaurant-style set up, and I'm sure the quality of the food will be more than adequate.

Here is a question of my own - if using the F lounge on NRT-ZRH-LCY and ZRH-LCY is timed at 2025, can I use the pre-flight dining area too?
