I spoke with Artisan Cheese, at 2413 California Street (at Filmore Street) in San Francisco. Artisan Cheese is well regarded by a number of Chowhound cheese lovers.
Artisan is receptive to setting up a 4 session cheese class for us. (They currently hold cheese classes in Pt. Reyes, 1 hour north of SF). They are now working on pricing, dates, and curriculum! It will probably be on a weekday night from 7-9pm at the store (central location in SF; parking will be fine at that time). I'll find out more early next week and will post details.
