Hands down the best Thai, nay the best oriental, food I've ever had (and I'm oriental). If you go, make sure you get stuff off their northern thai menu. I'm sure the other "generic" thai dishes are good but their specialties were out of this world. Crispy duck that still boggles my mind how anyone can elevate duck to that level of tenderness with melt in your mouth skin.
Flavorsome curry and salads with all the five taste sensations in balance. Portions are the best I've ever seen in any thai restaurant I've been to around the world, although I haven't been to Thailand to truly compare. It might not be the best in the world but surely on this continent it has to rank at or near the top.
Judging from how full the restaurant was near closing time on a Sunday and the number of Thai people eating, they certainly are doing things right.
