Greenhouse considers itself a "holistic and wellness center," rather than a simple yoga studio. And true, they also offer tai chi, various massages, accupuncture, pilates, and belly dancing, as well as our favorite Indian method of stretching and breathing. Oh, wait, I learned that from the Kama Sutra. What I meant, of course, was yoga. Greenhouse has small classes, in ashtanga, vinyasa, prana, and restorative yoga. My main complaint is that instructors sometimes don't emphasize the spiritual aspect enough, skipping the end-of-session meditationaclearly my favorite part, because it involves lying on your back.
