Definitely a hole in the wall...but one that you'll want to find yourself in.
The food is tasty. They have a simple, one page menu - and by one page, I mean there is literally one sheet of paper floating around. At first my husband and I ordered 2 servings of the veggie combo. One was definitely plenty, but I think because the other Ethiopian restaurants in town have you order two, I was conditioned. One order to share will fill you up. The $9 veggie combo included the red lentils, yellow cabbage, and collard greens. The injera is very, very good. They don't serve glasses of water, so grab a bottle from the front of the store and bring it with you.
Yes, the front of the store is a small grocery section. You can pick up some spices, rice, flour while you're here.
The dining space is very small, perhaps 4-5 tables. On both occasions that I've visited here, the place is full of other diners chatting it up or grabbing a quick bite. The service is friendly.
Make the drive out this way for a tasteful plate full of spice. Enjoy.
