The BA178 ?
Definitely one of my favourites. (Other opinions will vary)
You will get Brunch shortly after take off.
In WTP - That is usually Yoghurt and Fruit Juice plus the usual Main Course from Club.
There are usually two choices - something like Mixed Grill (Sausage , Bacon, Chicken & Scrambled eggs) and Pasta (Artichoke Ravioli on my last trip a couple of weeks ago)
Before landing there is just a snack box Sandwich / - piece of cake kind of thing. but that usually seems just enough to me.
For me, this is a great way to come back from the USA - avoiding the short night flights, and arriving in the evening a little tired and almost ready for bed at the same time.
Being in WTP allows me to be reasonably comfortable but encourages me to stay awake...
Enjoy !
