Nice large room/facilities...pleasant staff..you can eventually find an instructor & class that suits your style...
But the $18 per class is beyond most finances and not in the spirit of yoga.
Sure they offer the community class at $7...but you're lucky if you break
a sweat in it. An alternative is Pay what you can.
If you trust that people will pay what they can afford you might be surprised
with the turnout and positive effect for the community. An example is
YTTP in NYC...yelp it.
