Bit of an odd one:
I'm a big fan of pu'er bing cha teas -- you know, those pressed circular disks of multi-year old fermented teas which are a highly prized Chinese innovation (image: http://cdn3.volusion.com/fry26.b3umz/v/vspfiles/photos/PC030-2.jpg?1383811691).
In Portland (Oregon), a disk of cheap bing cha goes for $32 (1,038 THB), but I suspect with Thailand's proximity to China I could find some far cheaper (and perhaps of higher quality). I'm just not sure where to start looking, as I know the Thai aren't necessarily as crazy for tea as their regional neighbors.
In Bangkok or Chiang Mai, does anybody have any tips for where to score a decent selection of reasonably priced pu'er bing cha? Any good market regions in Chinatown, for example?
I'll also not be traveling with the tools necessary to brew any of this up -- would you have any leads on where to find travel appropriate infusers for the separated leaves?
