Basil Thai Fusion is one of the few Thai restaurants in Santa Clarita.  They use to be called "Kati Thai."  They offer Thai classics such as Pad Thai and different kinds of curries.  Their prices are reasonable and the ingredients are fresh.  Try their Pad Kee Mow (spicy flat rice noodle), black bean chicken, pineapple fried rice, cashew chicken, or Thom Kha Khai (a traditional Thai soup).  This is definitely the place to get your Thai fix, and you can order tasty appetizers (like egg rolls) while you wait.
