Best: Grenoble, France. They bragged about how good it was there, and that you didn't need to buy bottled mineral water.
Worst: Piece of cake, San Angelo, Texas. I could NOT drink the stuff without gagging, and it even made drink mixes and iced or hot tea taste bad. My dog wouldn't drink it or eat ice cubes made from it. Brita filtration AND Pur filtration did nothing to affect taste. Stuff was seriously nasty and actually damaged some of our pots, pans, and flatware after a year. Did I mention horrible? Makes me retch thinking about it. :disgust:
