I really love Archi's and its not far from you. Go east on 215 to Rainbow turn north (right) and its right past Sunset on the left side. The TomYum is very yummy as is everything else I have tried (the yellow curry is to die for).
I copy that on Lotus of Siam - I live in L.A. where there are better, but not by much, Thai restaurants - this is a winner and the city is very, very lucky to have it! Location is kind of not so great, but you forget everything when the plates arrive. Enjoy!
