That's a ways out. And a bit out of my personal knowledge base, lol. Sorry I know that's not much help. The best bet, would be keep trying new stuff until you fine something. There are legit strip mall restaurants outside the city.

Do you know where you are moving yet? Like what neighborhood?

Short answer is it depends on where you are moving to in DC. I too came from the Midwest. There 5 miles away was bassicly local. Here 5 miles is an eternity.
