Water Tasting #1

I always thought water tasting a little pretentious but if I am tasting drinks, why not water....right? ;-) I know at least one Fine Restaurant that has a menu entirely dedicated to bottled water(!), and with so many  'designer bottles' I am slightly curious to see if there is a difference between them all...
I will start with Fiji as I have read that this is the most refreshing, and it was! It comes in a clear square bottle with an attractive image depicting it's tropical origins. Certainly eye catching, but what about the taste? Very smooth with no 'oilyness' like Evian, and no metallic edge. Could I detect volcanic springs? Not really, but it did taste different to tap water! Conclusion: Very nice, but expensive. Someone else can buy it next time...
