Thai Orchid is a personal favorite of mine.  The Tom-ka-gai soup is superb and perfect for a cold day. A group of us (construction workers) order it in the summer when it is rainy and miserable outside, and it warms you right up as well as being far more food than most can eat in one sitting.  If you haven't been to Thai Orchid, I would recommend it strongly.  Beware though, it is family operated and they often shut the place down for weeks at a time for vacations and such.
