If you want to eat real Thai food and not tourist Thai food then this is the place for you. A little modest restaurant ran by 2 brothers. The food is just delicious and you can sample some traditional Thai food which you do have on menus in the tourist restaurants. Yai will also, if you ask allow you to watch while he cooks your food, if he isn't busy and he is soon to offer cooking classes. They both speak and understand English well, so recommending a new Thai dish isn't an issue:)
Situated just as you come out of Choeng Mon on the way to Chawang on the right.
Happy dining :)
