I don't know what the official FC offer on TPE is, because I've been offered the snack box a while ago (nice pate & snacky stuff like that- can't fully remember what was in them) , but I was also offered something from the basket last Monday (Bank Holiday) , which had a selection of oatie cookies, cake etc.
The basket job was what TPE offered before the clip boxes were created, but I must admit that I definately prefer the selection from the basket, as those honey & oat cookies were devine!
As for the 185s- I've only actually travelled FC on them before, but really enjoy the very comfortable seats (I usually get a table to myself), and the fact they recline (As per usual in FC). However, I must say that I really hated FC on 170308 between Hull and Leeds, and was glad to get on a 185 from Leeds, even though it was packed, and I was the only person in FC on the 170.
Also, you can't really put a price on all that engine thrash in the FC carriage, although it was very nice to experience the engine out of use from Manchester to Liverpool for a change, just to see the difference it made to the noise levels in the carriage.
