Disclaimer: I know Michael and Kim McCarty. I've eaten at the New York City restaurant, and the one in Santa Monica. I love them (the restaurants, and the people). If you're not familiar with either restaurant, it might help to know that the New York restaurant is the center of the media universe (in terms of eating, anyway). And the Santa Monica restaurant is the West coast equivalent.
To quote Harper Collins editor David Hershey (from the book): "Every generation has its literary feeding trough. In the twenties and the thirties, it was the Algonquin; in the forties and fifties, it was Toots Shor's; in the sixties, it was the Lion's Head; in the seventies and the eighties, it was Elaine's; and since the nineties, Michael's has been the place for media and publishing types to eat."
