This place is exactly what more ethnic restaurants in DC should be like. Eritrean food will remind you of Ethiopian, but it isn’t the same either. There is more bread mixed into the dishes for one thing, and the cuisine is overall less Americanized. The vegetables are less smoothed over. What you want to get here is the listed “Five Eritrean dishes” listed on the bottom of the menu, otherwise not further specified. Also get one or two of the “Fuls,” which are available for breakfast too. The Egg Ful is especially tasty. The wheat dishes are original.
Everything here is quite good, and the staff and proprietor are quite charming. A strong restaurant on all dimensions and also extremely cheap. By the way, maybe you knew the “old Keren,” but the place is under new management circa 2012 and is much improved.
