Tigist Hailu's Columbia Heights Ethiopian restaurant is the only Ethiopian place on Washingtonian's Top 100 Restaurants — a small, warm room serving the cooking Hailu learned from her mother in Addis Ababa. The injera is made fresh daily, the doro wat is the right move for first-timers, and the vegetarian combination platter is one of the best representations of Ethiopian cooking in America. For diners who want to understand why DC's Ethiopian community shaped the country's perception of the cuisine.
