For the highest quality and widest selection (250 loose-leaf teas from around the world, including exotics such as Malawi Satemwa Zomba Pearls), head to these outposts—the only two in the country—of the posh German chain (pronounced tee-SCHWEN-dnar). Prices range from $8.50 to $80 (!) for 100 grams—but you can get a free sample if you ask.
