Hey all, I'm in DC for a few weeks doing an internship and I'm looking for some good, local recommendations. I will eat just about anything but I'm mostly looking for super authentic ethnic places. Can anyone suggest a good Middle Eastern place, South-East Asian place or Korean place? A few factors to consider - I'd like to keep it relatively inexpensive (less than 20$) and I'm living in Georgetown, so anywhere close or somewhere off the Metro line or Circulator would be super.

Thanks in advance!
