I tried out Tadu Ethiopian Kitchen one day for lunch. It's a tiny hole-in-the wall in the Tenderloin, Ellis St & Leavensworth St.
I got the Vegetarian Combo $11.95. You gotta eat with your hands eating Ethiopian food - Right hand! You can wash your hands in the sink area in the back. 4 different veggie dishes on top of injera, a small salad with 2 dips on the top. More injera given in a small basket.
I liked my dish, red lentils were my favorite. Would like to try some meat dishes next time.
I paid Cash, not sure if they take credit cards.
