To Market To Market and I plan to be in Bangkok during April '09 and hope to be doing a cooking class.
It seems from this thread that either "Blue Elephant" or "Baipai" may be the way to go.
It's been nearly a year since the last posts here - does anyone have more to add/recommend?
EDIT: It seems we'll be there during "Songkran". Is it likely these will close on those days?
