Dukem is definitely not the cheapest Ethiopian fare to be found in Toronto (go to Nazareth for that) but nor is it super pricey.
What really stood out for me about the food at Dukem was that it was not overly greasy whatsoever...it fact it wasn't greasy at all. Even the injera bread underneath both our veg and meat options did not become too saturated with oils (as is the norm for Ethiopian food I've had at 4-5 other places in Toronto).
My Yelp buddy and I shared 1 vegetarian plate ($12) and added a lamb dish ($14). Note that the prices on the menu INCLUDE tax (bonus!) So $26 for two people is not too bad. Food portion was large and they brought plenty of injera bread so we didn't have to ask for more.
Another thing I liked about Dukem is the service was good and the food came out within a reasonable time - another surprise for an Ethiopian place. I'm usually left agonizing over why the food is taking so long.
Decor was OK. The place has only 7-8 tables. Waitress was very friendly.
