This is my absolute favorite place to buy or drink tea. The range of standard and exotic teas they have is impressive (think wall of tea canisters they need a rolling library ladder to reach the top of) and the quality of the ingredients they use is outstanding. There have been many times when I've gone in for recommendations based on other teas I've liked and each keeps getting better and better. There's a small cafe in the back that serves tea, scones, cookies, and inventive things like tea floats. You'll be waiting for a long time if you try to come on a Saturday and sit down at a table. Weekdays are best. Definitely a gem in SoHo.
