Do you need a first class ticket to buy food on a first great western train?

Can you buy on a first great western with a standard ticket as well?

Best Answer:

Philip: No you do not. The buffet car is available to both First and Standard Class ticket holders and the few First Great Western services offering full meal service in a dining car will serve both passengers from Standard Class and First Class

Philip:
As far as I am aware, full meal services are only available in first class in all UK train services. However a range of hot and cold snacks, drinks etc. are available from the Buffet or trolley service for standard class passengers
