Yanzi Noodle House and Taiwan Style, web site, 10955 Fairfax Blvd, Suite 108, Fairfax, VA (between T-Mobile and Red Wing), 301-777-8888 (Metro Trip Planner – opens in new window) [WaPo | Reddit | Ylp] They moved from Rockville, MD.
One of the most authentic Chinese places around. Their main dishes are the noodle soups from southwestern China, sour and spicy together, first-rate, but note for me they are not enough for a full meal. The rest of the menu has southwest Chinese influences, though not as far west as Yunnan province. Recently I had the tofu, pork, and mushrooms dish – a home run and again with authenticity off the charts. What they have varies wildly by day, so you can never quite be sure. They don’t seem to have the Taiwanese dishes at all any more. Highly recommended, this is not an “all purpose Chinese restaurant,” but a real Fairfax experience.
