-- any good tea store in los angeles chinatown?--

i like Wing Hop Fung ( http://www.winghopfung.com ). 2nd floor has a
huge variety of teas, and you can try before you buy. they also have a
good selection of teaware at reasonable prices.

Far East Plaza, across the street, often has some ok teas, too, but you
can't try them first. They're yinzhen is cheaper there (and when I last
had it, better than WHF).

there's also a Tenren in the same plaza as WHF: http://www.tenren.com
Though their selection is limited and...see the recent discussion on
here for more opinions of their tea...i've liked their oolongs. That
particular store will often ignore non-asians, so if you're not asian,
be sure to wave your arms about and scream if you need help.
