He's the newish quizmaster on University Challenge.
Off topic aside follows. He always sticks in my memory for a restaurant review of Alimentum in Cambridge. The restaurant is long gone, although another has replaced it. The reason his review is memorable was the absolute clanger of not realising the restaurant was situated in a part of town where some of the most expensive mansions can also be found. Where Pimms o'clock was practically invented.
Nothing can be done to overcome the problem of location. Far from the city centre, Alimentum is situated on a busy road, next to the main railway bridge, opposite a giant Travelodge, under a set of new flats, and in view of the giant club where I used to go raving. Punts and Pimm's o'clock this ain't.
