Bangkok Food Tours
Although I did not (yet) try it myself but I like the idea that 3 young Thai people had "Introducing Thai food to foreigners but in another way as normal and a little bit more". They organize walking tours in Bangkok to explorer the Thai (& others exotic) kitchen both on the street in restaurants. And while you are on tour not only exploring the food but also the rich history of culture and architecture of Bangkok.
I like the idea very much, next time when in Bangkok I will try to make a tour with them! As food is such an important part of Thai culture (the 3 young people could not do without it while studying in the USA) I think it is a great way to understand more of Thai culture as you read in books. And it also gives a chance to look to cultural Bangkok in a different way. See Bangkokfoodtours
