Currently, for the sake of simplicity, it just says "Food", since most passengers are just interested in whether food is available inside the train or not. Some frequent travellers or rail fans might be interested in where the inside-train food is coming from. This feature was therefore accorded low priority.
We shall put it on the pending list, and get to it eventually. Other related information items that can be added are the "Food Menu" for Rajdhani/Duronto/Shatabdi trains and so forth.
Thanks for the suggestions.
