In 1992's The Player, Tim Robbins' character, the consummate Hollywood insider, showed his sophistication at restaurants through his ability to differentiate among various kinds of bottled water. But today, that same Hollywood macher would never ask for anything but tap. Because of the environmental costs of producing and shipping bottled waters, more and more chefs are offering only filtered tap water to customers. Mario Batali and his business partner Joseph Bastianich stopped selling bottled water at their New York City restaurants Del Posto and Otto earlier this year, and eateries in Florida and Massachusetts are also serving only tap. The U.S. Conference of Mayors voted in June to recommend that City Halls stop serving bottled water even at special functions. Once hip, bottled water is now unforgivably '90s.
