I like Ethiopian food, but I just had it for the first time with Anthony11 a few weeks ago in Seattle, so I'm not exactly an experienced guide. But anthony is vegan, and when we ordered the veggie plate there, we didn't have to make any special requests. Everything was already vegan, and it wasn't a special veg-friendly restaurant either. It seemed to be a fairly omni place overall. FWIW, every Ethiopian restaurant I've looked up here in Houston also has a vegetarian plate, so it seems to be a fairly veg-friendly cuisine.
