I've come to the conclusion that my favorite types of restaurants in DC are the small, cozy places with fantastic food (somewhat neighborhood restaurants). I find them great for out of town guests. Currently my 2 "go to" places are
1) KUNA - Love this place and food is always excellent along with the service. This is the epitome of the little jewel in my book.
2) Bistrot Lepic - This is a magical place that thas the best veal cheeks that I've ever had. Great upstairs wine bar as well.
What are some others that are worth exploring?
