Light rail construction has recently displaced them, and they have now relocated to 16876 Southcenter Parkway, Tukwila, near the mall. phone 206-575-3366 in swankier digs in a strip mall near Toy'R US.
I like Thai food , and feel lucky that we in Renton have Thai on Highlands and Royal Orchid.
They're good, but they're no Bai Tong. Bai Tong is pretty amazing, and very reasonably priced.
The place is very pretty and comfortable, and very professionally run. Menu items and flavors are different that most other Thai places, for example they feature a steamed salmon curry in banana leaves. Sauces are more complex than at other Thai places, and the place is just a notch or two better than most anywhere else. If you like Thai food, you'll love Bai Tong.
Prices are also a dollar or two per entree LESS than other Thai places. Go there!
