Ethiopian near Long Beach?
Unfortunately, unless there's one hiding in Inglewood that I don't know about, your choices are three:
1. The "Little Ethiopia" district that stretches down Fairfax a block or two from Olympic Blvd. in Mid-City -- many Ethiopian places, the best of which IMNSHO is Meals by Genet.
2. Fassica, which is on Washington and Motor in Culver City.
3. Merhaba, which is on Ball Road between Beach Blvd. and Magnolia Ave. in Anaheim.
