I remember once being detached to RAE Farnborough about 1981/82. At dinner one weekday evening the mess steward asked me if I was staying for the weekend (I was) and if so, what would I like for my Sunday lunch. I aasked him what was on the menu and he replied that it was anything they had in the kitchen. So I went for the traditional Roast beef, yorkshire pudding etc. I seem to recall the chef also made an excellent rhubarb crumble with custard for dessert.
Happy days.
