WTHN just opened in the Flatiron district. Really cute. Had been wanting to try acupuncture but not sure where to start. WTHN makes it easier and of course a bit instagrammable for millennials :) I thought the space was very nice. I felt instant relaxation -- something I never felt before. Was very interesting. I think the prices are reasonable ($65 first time, $75 or 85 after depending if you're a member). Can also buy some other products. A good business idea.
