This depends on the type of tearoom/house you'll be starting, but Adagio does have great service, and I believe offers a good value for the price. In fact, their prices and quality in my opinion is better than Harney, S & V and others listed above. I highly recommend Adagio for flavored teas, Empire Tea Services (www.empiretea.com
) for ceylons and other blacks, SerendipiTea for their fantastic, creative blends, and Infuze for their superior greens. Hope this helps!
