Finally finished my survey of Chinese-Vietnamese restaurants in Portland. Four of these places (the last four in the list) are similar in style and menu. Chino Saigon, however, includes a lot of Thai dishes and is owned by a Mexican. Yet, it was actually decent to good.
Also decent was Jin Wah. The best was My Canh. Thien Hong and Vien Huong were horrible, however. (Just talking Vietnamese food here.)
My Canh is worth making a destination on occasion. I really enjoy their claypots and they're a lot cheaper than Pho Van's. The chicken in ginger sauce is sweet and piquant. Their soups are good with clean, flavorful broths. They have a good variety of them, too. Watch for the crispy quail on the specials board.
Jin Wah and Chino Saigon are worth going to if you're in the neighborhood, although the Jin Wah on 82nd has a lot of competition within an easy drive. Broths are tasty, meats tender, noodles cooked competently.
Thien Hong's and Vien Huong's Vietnamese challenge for the worst Asian food I've ever eaten. I'd rather eat at the Safeway Chinese deli or Panda Express. At least they're just overly sweet with everything tasting like it has the same commercial sauce in it. Thien Hong and Vien Huong make food that is actively offensive to the palate. Thien Hong's duck soup tastes like sawdust broth. Vien Huong's meat for their pho tastes like they found something wrapped in butcher paper in the deepest corner of the freezer and decided to serve it up.
