No... CX 839 the departure at 2pm will have the full main meal served after takeoff with caviar and salmon board, soup, salad, four main course choices, dessert, cheese and fruit board, and parlines... I flew this flight more than twice, so I am sure about the caviar service.
the only flight without caviar and salmon is the 2am departure from YVR on CX 889. Since those items are offered on the previous segment from JFK to YVR, and most passengers opt to sleep on the second segment... a light meal will be served after takeoff, all night snack on demand menu, and a full breakfast prior to arrival.
Don't worry Seat 2A! You will get your caviar if you are on the afternoon CX 839 to HKG from YVR.
About the second meal, it is often called a supper... a very basic meal with fruit appetizer, three main course choices (or two), and then pralines. Very basic light meal! A bit too basic if you ask me... but you can always ask for extra main course, as not many people actually eat the second meal. It is almost 2 or 3am in West Coast time when they serve the second meal...
