I happened upon Dalo's when looking for vegan dinner options in the neighborhood. Dalo's has a nondescript entrance on Williams and is located inside some kind of community center building. Despite the entrance looking more like a back door, the decor inside is very nice. There is a restaurant seating area and also a bar section.
Dalo's has several options listed as vegan, which are available a la carte, in the "vegan platter," or on the buffet ($11-12), if you are there at the right time. We opted for the buffet, which had plenty of options - injera (spongy bread) with a simple salad (seasoned with vinegar), seasoned rice with red kidney beans, red lentil wat and yellow split pea wat, a cooked cabbage dish, and a cooked gomen or spinach dish. (Otherwise, there were two other dishes with meat in the buffet).
I don't have Ethiopian cuisine often (so I'm not a connaisseur) but the food was satisfying, the server was very nice, and the coffee was good too.
