Guilt-Free Sparkling Water

Thanks to progressive minds at local restaurants, I can now have my bubbles guilt-free.
I first spotted AquaHealth's house-filtered sparkling water at Poste (pictured above). The latest spot to offer the elegant refillable bottles? The brand new (and piping hot) Cork Wine Bar. (They're also serving my new favorite fries, liberally sprinkled with an addictive mix of lemon zest, parsley and salt.)
The AquaHealth system allows restaurants to filter water on-site, add optional carbonation and pour it into reusable glass bottles.
Spotted AquaHealth anywhere else around town?
