For those in the North Hollywood, CA. area,
I meet with a very small group to teach basic Mandarin Chinese once a week at the Starbucks on Laurel Cyn and Riverside Dr.
There is no cost and no book needed. (although I do appreciate the occassional free coffee).
Very informal and flexible. Very loosely structured.
Tuesdays at about 7PM.
