I've been a customer of this restaurant since it opened (in, I believe, 1993), and I've never had a bad meal. I've ordered most everything on the menu. Food is always carefully prepared in complex spices, hot but not overwhelmingly so. Meat dishes are tender. Portions are good. The way some of the dishes are prepared can change with the mood of the kitchen, and so ordering the same dish can often yield a different result - which might be a minus for some people. This is particularly true of the vegetable dishes.
The kitchen and service are run by the owner. He's gracious and attentive and good at explaining menu options for folks who are unfamiliar with Ethiopian food or who want to try new things on the menu.
The menu occasionally veers into other kinds of cuisine - for example, they make a killer jerk chicken.
My favourite vegetable dishes are the red lentils, the ful (a stew of fava beans), and the green vegetables - usually an interesting, spinach-based stew. For meat dishes, the jerk chicken is very good, and the African lamb (boneless, made with a spiced clarified butter) is very good.
Not on the menu, but usually available, is ugali, a cornmeal dumpling served with a delicious (and quite spicy) wat (sauce).
I think the best way to eat here is the combination dishes, where several different items are served on one platter of injera to share. It's a good way to try different tastes, and the value is good. I will often go in with a friend and order the vegetable platter - three vegetable dishes for two people for (I believe) $16 - and leave it to the owner to choose which to serve.
There's a pretty standard selection of beer; they also carry Red Stripe.
As for ambience: the place is comfortable, cozy, painted in warm colours. Nothing fancy. I enjoy it.
It's easy to feed two people to the point of bursting here for $20. For me, this restaurant is one of the most reliable inexpensive options in Vancouver.
