We took an evening class and overall we had a nice afternoon with some people we meet and the very entertaining teacher.
But having tried other cooking classes and travelled for 12 years in Thailand. The content was quite shallow and the level to low. And you could feel the teacher have said the same things 100 of times - with quite limited English skills. He could not answer on specific questions about the food or vary from his normal script.
Further more it is very expensive 1800B pr pers. compared to what you get - there is no recipe book, water or Anything provided. You pay for all you drink And they designed the course with quite a lot of waiting so you need to buy stuff.
We would recommend you to try another cooking class. Preferably in Chiang Mai!
Our impression is that this is a money machine with no soul.
