 According to the article, what is Condé Nast?
Let Si Get This During a typical lunch time at the Royalton Hotel restaurant in midtown Manhattan, The New Yorker 's Tina Brown might be installed at her usual table, and Vogue 's Anna Wintour might be at her usual table (chewing on her usual meal--a $25 hamburger). Vanity Fair 's Graydon Carter might be there too, although he has transferred his main allegiance to a place called Patroon. Filling out the room are other editors, publicists, and writers from these magazines and GQ and House & Garden and so on. Some of the lesser fry may even utter the Condé Nast mantra--though it is hardly necessary at the Royalton--as they grab for the check: "Let Si get this." S.I. "Si" Newhouse Jr. and his younger brother, Donald, control Advance Publications, one of America's largest privately held companies. Donald tends to Advance's hugely profitable newspaper, radio, and TV holdings. These are the 15 Condé Nast magazines, including (in descending order of fabulousness) Vogue , Vanity Fair , GQ , Condé Nast Traveler , House & Garden , Allure , Details , Self , Mademoiselle , and Glamour ; ; and Random House. The expense-account lunch is a hallowed journalistic tradition. The magazines account for more than a quarter of daytime revenues at the Four Seasons and the Royalton. At Vogue and Vanity Fair , almost everyone has a "working lunch" every day . (One of my favorite Condé Nast stories is of an editor who had just been promoted to an extremely senior job.
