I just tried out Sala Thai, which just opened in the same shopping center as Trader Joe's (on 156th in Bellevue, just south of Uwajimaya--I think Northup is the cross street).
It's okay, but it's no Lotus of Siam. I started with the lamb satay ($8.75 for 5 skewers). It was good: mild lamb with curry, accompanied by the ubiquitous peanut sauce, cucumber-n-onion salad, and white toast.
Next was lemongrass chicken (also $8.75). Marinated chicken, charbroiled and served with (oh, crud, just forgot the name of the sauce) on the side, and accompanied by another pickle-type salad.
Design-wise, they're going for an "economic elegant" sort of look. Crisply-dressed waitrons, flowers on the tables, salad *and* dinner forks, visible wine bottles, fairly aesthetic plating...while still keeping most of their food in the sub-$10 range.
Food quality is decent, but I wasn't wowed. It's fine for the price range, but frankly I'd prefer to spend a bit more money and go to Mayuri, Shi Lin, or that Italian place in Crossroads.
I'll probably go again to check it out after they've had time to settle in a bit.
