I flew CX254 just 2 days ago which leaves even later than 252... the service was refreshment and brunch... the "refreshment" in F was actually pretty close to a full dinner service... caviar, apetizer, soup, entree and dinner... brunch service consisted of juice, fruits, breads, and entree.. of course, when you are in F, you can pretty much have anything on their menu for that entree, including the refreshments.. I had a bowl of noodles for that. The meal services are more than enough..
