Most taste testers agree

Tap water is at least as good as bottled -- in Chicago in this case. (Thanks to Chicagoan Gary Wilson, moderator of Great Lakes Town Hall.)

The tasting was done as part of a kick off for the "Think Outside the Bottle" campaign in which green-minded restaurateurs are joining the likes of Alice Waters and Mario Batali in banning bottled water from their restaurants in favor of tap. The rationale is that bottled water creates garbage and produces carbon emissions in transport. The campaign is asking local restaurants to sign a pledge not to serve bottled water.
