having grown up in dc, and subsequently having fled to nyc, i've always been pretty down on the place as a food city. but i have decided to head home this year with an open mind and so i am putting myself in the hands of you knowledgeable people.
i'm looking for the best of the following:
(northwest preferred; the parents don't stray far)
-something vaguely upscale, nothing too trendy, or phenominally expensive.
-thai, chinese, or otherwise --informal, cheap, authentic.
-Sushi. I've only been to Sushi Ko. Where else should i visit?
Other ideas are, of course, very much encouraged.
