Addis Abeba in Richardson (75@Beltline behind 7/11 if you enter from Beltline) http://chowhound.chow.com/topics/447656
We go there once a month and love their beef wot. Their Kifto is also good.
The only thing is when we were there a few days ago we noticed their food changed a bit (it was less spicy and wasn't as good as it used to). They used to serve the salad on injera along with wot and other dishes, but they didn't this time and I had to ask for it. They also used to have lettuce wrapped with the beef in Kifto, but not this time. The waitress had changed, too.
I asked the waitress if the chef changed and she said no.
