How much would you pay for the best water on earth?

I should have known by the way the waiter looked at me apologetically through his hip black glasses. By the way he told me there was a charge for filtered water, I should have known it would be a large charge. This was no case of being tricked into buying water. Still, how could I have known that I would pay seven dollars for a carafe of filtered tap water?

In case you haven't tried it, Los Angeles agua tastes like pool water so I didn't want to go the tap route for my first Thomas Keller meal, even if it was just lunch. I wasn't drinking anything else, so I knew I'd really notice it. It was a special occasion. I was taking myself out. A charge? That's fine, I said, thinking, it's not one of those slim glass bottles or anything. It's just filtered water. It was all good. I was even feeling a little posh as I sat reading my book and waiting for my quiche. However, I was not prepared for filtered water to turn my bill into a 42-dollar one-lady food festival.  LINK
