You need to know 3 things for eating at Nazareth:
1) The food is fantastic. Some of the best Ethiopian food I've had, and better than any other Ethiopian food I've had in Toronto.
2) The food is very cheap. The veggie combo (which is what you should order) will serve 2 people for just over $10.
3) It will take forever. You will slightly annoyed at the speed with which you are seated, your order is taken, and when your food comes out. Just when the "hangry" feelings start to peak, your food will come, and all will be forgiven. The staff all mean well, and the owner can be super friendly and sweet, they're just overwhelmed.
There's honestly not too much more to say about this place. Great food, great price, annoying process. It's worth it.
