But cost-cutting at Conde Nast is not quite like cost-cutting at other publishers. For example, on Oct. 13, the men's magazine GQ will host a party in Washington to promote its list of powerful capital players, to appear in its November issue. The party is upscale: it will be held at the 701 Restaurant, known for its caviar and live piano music. That is not the only expense involved. Several editorial employees will travel from New York for the evening. And they received an e-mail message recently reminding them to limit their expenses for the night -- to $1,000 a person.
