I have never appreciated any kind of food associated to airport, except for this small place inside Hong Kong Intl’ Airport terminal 2: Sawatdee. Truth be told, another time I ate there (dumplings at Maxim) was quite good actually. Sawatdee — like its name suggests — specializes in Thai food, and is serious about it. I have tried Tom Yum Gung, Green Curry, Pad Thai, and glutinous rice with mango and coconut milk there. All were awesome and at a reasonable price.
Green curry: awesome awesome awesome. My biggest worry when I order Thai curry anywhere is that the coconut-y flavor would be watered down. Not the case here. The broth was perfectly seasoned with loads of chicken. It looks great as well.
