A clean and relaxing studio with a great intro promo: $40 for one month, unlimited. You can use the pass at both locations (though I have yet to go to the Uptown Moksha).
My favorite instructor is Jen M. She smiles a lot and does a great job of creating an informal and inviting atmosphere. She is excellent with her timing (i.e. does not lose track of people in poses when correcting others) and is very helpful at suggesting how to perfect a pose. Sarah is also good.
For those of you who don't know about Moksha, it incorporates many Bikram-style poses in a less structured and strict environment. Basically, it is friendly Bikram and workout is just as good. The room is hot so you better like to sweat.
Another great addition to the St Clair West hood!
