From the author of Paris to the Moon, a beguiling tour of the morals and manners of our present food mania, in search of eating’s deeper truths.   Never before have we cared so much about food. It preoccupies our popular culture, our fantasies, and even our moralizing. With our top chefs as deities and finest restaurants as places of pilgrimage, we have made food the stuff of secular seeking and transcendence, finding heaven in a mouthful. But have we come any closer to discovering the true meaning of food in our lives? With inimitable charm and learning, Adam Gopnik takes us on a beguiling journey in search of that meaning as he charts America’s recent and rapid evolution from commendably aware eaters to manic, compulsive gastronomes.
