I used to love getting the early morning train from London to Norwich, when it was run by Great Eastern.
The train had a proper dining car, where standard class mixed with First Class (much to their chagrin) for breakfast. You paid about £11 and you got a cooked breakfast of gargantuan proportions (with some of the nicest sausages and bacon I've tasted), with good coffee flowing freely. You could eat as much as you liked - the waiter constantly hovered to offer more eggs, bacon, sausages, mushrooms etc.
There seemed to always be one of the same two couples running the show, no matter which train you were on. One couple were two old queens (one cooking and one serving) who constantly bickered and were an endless source of amusement for all diners, or a lady of advanced years and her male cook, where it was like being fussed over by your mum.
Now, you're lucky if you can purchase some cardboard and gristle that's been nuked in a microwave - and the coffee is shit!
