Regular service - dinner served shortly after departure, and a pre-arrival 'snack' (which I don't think is 'afternoon tea' at that time) shortly before landing. Pretty standard service; I've done this route a few times in F and never thought the catering was out of the ordinary for F

Bear in mind that F is 'dine on demand' anyway now - I do on these late flights often ask the crew to hold off and just serve the 'main' meal later in the flight as that stops me falling asleep on board later in the flight (which I find helps with jet lag, to stay awake until get to hotel at 10-11pm local) and allows me to get work done before I relax
