If you have not had enough of Tom Yum after feasting on it everyday of your Bangkok trip and happen to have the last 150 baht left at the Suvarnabhum airport . I truly suggest you get this from no other place but King Power DFS. Its only available here. Be warned, don't even think of bringing it back home once you start on it - even if they comes in individually packed sachet. It's highly addictive!
