The owners of the Solom minimart at the intersection of Rainier, 39th and Pearl have expanded to a little cafe — sign says American/Ethiopian breakfast 8am-9pm and then Ethiopian lunch/dinner for more limited hours; we live nearby and have been keeping an eye on the progress; it just opened last weekend.
Stopped in on the 16th for an early dinner with two friends. Their menus aren't done yet, so the waitress offered chicken, meat or vegetarian combination plates. We opted for 3 vegetarian, and all ordered hot tea. One big shared platter with greens (collards or chard, not sure which), a tasty potato-carrot dish with lots of butter, yellow split peas, red lentils and a bit of salad plus two pieces of injera — plenty for 3 without being stuffed — came to $8, plus the tea. I almost hope their prices go up, that doesn't seem expensive enough to stay in business!
The tea was simply bags of Lipton, probably from the minimart. The restaurant side is nice — big windows, a few comfy padded booths. Very relaxed and unhurried, like I think Ethiopian restaurants tend to be in general, but if you're in a rush, you'll likely find it annoying.
