Walter Rhee, the extremely well-regarded Korean/pan-Asian cooking instructor who formerly taught regularly at the Cambridge Center, moved to Hawaii to teach some years ago. But he makes occasional treks back and he'll be doing it this fall.
Find his courses by searching the Cambridge Center's course catalog, or use this link to Walter Rhee's classes. There's a class on kimchi, a class on Boston's Best Unexplored Asian Restaurants. The course description for that one recommends elastic-waist pants. How can you resist?
