Om Yoga has some great things going for it: location and facilities. Can't beat its proximity to Union Square and it's very large and very clean. Changing rooms and bathrooms pretty spacious compared to other studios. Having said that, I think it's sometimes hit or miss when it comes to the instructors. People who work there are friendly, helpful and there's store with some nice yoga gear, etc. Also liked the additional events and meditation classes. I think if you are new to yoga, this will have everything you want. Seems to draw a yuppie crowd.
