Emame's Ethiopian food cart on 9th and alder was my suggestion. One of the only two Ethiopian restaurants In Portland that I keep going back to. Jarras was nostalgic and tops in my book, but they closed after being in business for decades and deciding that it had been long enough.
There are a couple of choices around town still - Queen of Sheba, Bete Lukas, Enat Kitchen, E'njoni cafe, Emame's, and Aberus (amongst others).
The nice thing about Emame's is the quick service, but unlike Rahels(SP?) at cartlandia on 82nd, the food at Emame's is superb in taste.
For sit down family style IMO the best Ethiopian left in town is Aberus. The one negative is I feel like they use A LOT of oil in their cooking. Still though the tibs with berbere is delicious. Aberus is more traditional and cheaper than some of the other alternatives like Bete Lukas which has great quality food, but the flavors aren't very strong like they were at jarras, and that's what I look for when I eat Ethiopian.
Portland as great a food town as it is, still isn't at the top of the Ethiopian game. Washington D.C has some really good Ethiopian restaurants.
