Sorry, I'm with broadgage on this one.
Having travelled up to London from Penzance on an
HST▸ with an open buffet, the relief to walk up to it, order food and drink, then a walk back was good.
We returned on an
IET▸ with no trolley sighting until it appeared at Redruth.
Although we purchased some food and a drink at Paddington (having seen it was an IET), we were parched by Exeter, and gagging beyond Plymouth.
As the train was overfull there were many grumbles I heard in the carriage we were in about no food or drink being available.
To be fair to the customer host(s) they made several announcements on departure from Paddington to say they wouldn't be able to move through the train.
That said, there was only one announcement between Reading and Exeter, and none after Exeter.
I guess from TG comment that makes it 2 votes for a buffet and 98 against a buffet!
Entirely fair comments GBM.
My "long distance" travel by train tends to be Paddington (or occasionally Reading) - Plymouth......given the variety of food and drink available to take away at/nearby either of those stations, far superior in quality and far better VFM than that available on a train, I simply make sure that I stock up before departure - always carry a bottle of water anyway to guard against being "parched" - looking around the train it's clear that many do the same.
I do get that those travelling from somewhere like St Erth to London aren't as fortunate in that respect.
On my last High Speed Trains (HST) trip the buffet was open but doing very little business with a very limited range and it could only take cash because "our card machine isn't working" - sort of sums it up.
If there was sufficient demand for a buffet and they were profitable, they would have kept them. Travelling Chef failed because ultimately it was producing mediocre food that few people wanted at a high price.
The Pullman will probably survive on its novelty factor (and because it's subsidised by Broadgage!)
