Tom kha gai (ต้มข่าไก่) is a very popular Thai dish, and you can find it in Thailand at everywhere from nice restaurant to street food rice and curry stalls. The base of this Thai soup / curry, is coconut milk, so it has a rich and creamy flavor. Though it would often be listed as a soup, in my opinion tom kha gai (ต้มข่าไก่) is more of a curry due to the way in which it's eaten. It's served in a bowl along with plate of rice on the side, and it's usually scooped by spoon by spoon onto the rice and eaten bite by bite. In Thailand, most of the time it's eaten along with a full spread of Thai dishes to make a complete meal of well rounded flavors.
