Well, I dunno but it sure tastes like it. Had a break in the University Combination Room today - right in the centre next to the Senate House, Old Library, King's College etc. It's a function room for university staff and serves the most godawful coffee and tea - but quite nice cake. You can read about it here but the main points to note are the original wooden ceiling (detail below), the William Morris Carpet and the elephant tusks on display - a gift from Ethiopian Emperor Haile Selassie I. The ceiling really is astonishing.
