After hearing about it for years now, I finally tried Zenebech Injera. It is a true hole-in-the-wall. I don't begin to compare it to the great Queen Makeda, except in decor. It's good. The best thing about it is they have a sampling platter of various meats and veggies in one order. The name of the dish appears on the menu (I forget what it is) , but just the name not the description. You have to ask. At $13, it is a great deal and gives you a little bit of everything. We also ordered the nech tibs, which were immersed in a liquid and served in a bowl. This was a very messy albeit delicious dish.
Parking has now become very challenging in the neighborhood. Most streets now have absolutely no visitor parking, not even for an hour limit. We parked on a tree lined street where one of the signs was obscured by a tree and got a ticket. As we drove away, I saw that almost all the streets now completely prohibit parking except for neighborhood residents. This is a new low for DC that has not been seen in Georgetown and other very busy neighborhoods.
I don't have an answer to your question, but you should definitely go there! I finally tried it a month or so ago, and I've already been back three times! The most amazing vegetable combination and have enjoyed the ground beef meat dishes best. The doro wat (chicken) is the only thing not worth ordering. Love love love this place.
