The is a breathtaking studio with many talented teachers.
To cut to the chase:
PROS: an abundance of natural light and nature around the studio, great instructors, student discounts,
CONS: no yoga before work (why start morning classes at 10am?!), instructors too often send subs, a snail-paced the credit card system often leads to pre-class gridlock
Overall a great place with good instructors.
ADDENDUM Sept. 2009:
The credit card issues seem largely solved and the studio is so lovely and warm. They also have reasonable 2-month or student passes. However I maintain they need a webmaster to help you understand when a sub is coming or like this week when they are on a summer break schedule. Other studios are able to do this and it can be a huge disappointment to show up for a class that is cancelled or for an instructor who has a sub. With a better handle of their website, I think they would be close to perfect. Overall do not overlook this studio, especially if you like "Flow" forms of yoga and instructors who know their stuff and want to assist!
Pros: instructors, studio has so much beauty, classes are appropriately paced and skilled
Cons: too many subs, no early am classes, a slow credit card system
