Over the years that I have been making the journey out of town to these events, one restaurant has continually fascinated me. Just by a busy junction, across the road from the Wheatsheaf pub, is the Virginia Water branch of Chiquito. Each time I pass, late for lunch in the De Beers dining-room, or overdue for cocktails in the Cartier marquee, I pause at the traffic lights and gaze with interest at this establishment. Its green-and-yellow neon sign lures me like a Lorelei, seducing me with its siren song. It looks so dismal, so spectacularly out of place that I promise myself to stop in on the way back for a quick quesadilla but, of course, I never do.
