Just in case you haven't guessed from the attire of the ladies delicately tucking into their meals, this picture is from the 1970's. May 1979, in fact and marked the opening of the Jubilee Line. At Bond Street station passengers were treated to a string quartet and a nice meal.
If I was travelling quite a long way on the Tube, I'd like to have a meal. But it'll never happen again will it. You'd need to go back to the times when there were first class compartments on the London Underground (a Victorian and Edwardian trend).
Goodness knows what sort of premium you would have to pay if there were first class carriages on the Tube now. But I wonder how many people would be prepared to pay it? You'd have to be guaranteed a seat. Walkmans and mobile phones would be banned. Your Metro would be freshly ironed and you could have your own personal announcer, politely telling you which stations you were approaching. He or she could also give helpful information about the area. Any other suggestions for a first class service?
Speaking of polite announcements Martin sent me an announcement when his train finished at White City. He said "usually when that happens we get an "All change please", or the rather rude "Please leave the train."
