Jay Rayner's book "The Man Who Ate The World," makes for very enjoyable reading. Rayner combines travel and cultural details with food and restaurant reviews from his visits to Moscow, Tokyo and Las Vegas, among other cities. Along the way he delivers his sardonic take on local and international trends, mores and peccadilloes.
He is also known from his judging appearances on Bravos Top Chef and as a columnist for the London Observer.
