New to DC area - Restaurant suggestions for Arlington and area
The numerous responders to your original query have identified many good restaurant options (great minds think a like!). However, I am shocked(!) by their failure to provide you with a link to Tyler Cowen's webpage. http://tylercowensethnicdiningguide.com
You may not agree with all of Cowen's comments or his sense of humor (which I enjoy), but if you are adventurous, the info he provides will vastly expand your ethnic dining horizon in the DC metro area by leading you to places you'd never consider looking. (Note that he also writes very interesting pieces for the NYTimes--look for them in the business section.).
