As a guilo trying to figure out how to plug into world tea culture, Ito En is a great place to start. As Ryan notes, their NYC store is off the hook. Makinohara Sencha is a great baseline to acculturating this Texan’s taste buds to the finer things in life. I have no doubt there are better teas out there, but as the first step in a lifelong journey, this is a good place to start.
