DC Metro Food Tours is the area's premier source for food tours and culinary events that bring together history, architecture, and cuisine in a variety of different venues and historic neighborhoods.
One Sunday morning, I toured an enthusiastic group of University of Maryland staff and graduate students into the heart of the world's largest Ethiopian community outside of Ethiopia, located along U and 9th streets NW, in the historic 19th-century U Street and Shaw neighborhood. They boast over 45 restaurants in and around the D.C. area, with approximately half of them in the vicinity of U and 9th. One of the places I took them was a low-key, hole-in-the-wall called Zenebech (named for the family that owns it) where we feasted on "doro wat," a spiced chicken and egg stew regarded as the Ethiopian national dish.
Oh and by the way, forget the utensils, we eat the Ethiopian way with the right hand on this tour and food is served family style!
The Little Ethiopia Tour and other DC neighborhood food tours are available through the DCMetroFoodTours website.
