During the week, Harney and Son's tea tasting room serves free samples of two of its teas from around the world. On the weekends, when the shop tends to be more crowded, there's one tea available for sampling. What if you'd like to try a tea that's not being brewed that day? You've got two options -- you can ask, and if the store is not at all busy, you might get lucky. Or, you can always head to the tea lounge out back and settle in with a tea pot.
