I'm not sure what the last reviewer looks for in asian cooking, because my wife and I love Watercress AB! We just moved here from VA (outside DC), and have been searching for a place like this.
We love a kitchen that can provide delicious recipes from Japan, Vietnam, China, etc., and this kitchen delivers wonderful food. Add to that the warm, welcoming presence of Lily (co-owner, who remembers your name after meeting you only once) and beautiful seating areas, and you have a terrific dining experience.
There was one small issue with the dish I had ordered, and it was immediately address and a new dish sent out to the table within minutes.
We have discovered that there are a LOT of mediocre (or worse) asian restaurants in and around Redmond. Watercress does not settle for simply matching them; it blows them away!
As an fyi, neither I nor my wife work at this restaurant (as suggested in the previous review).
