Aside from texture/taste of falafel and pita, I usually can't discriminate much between Mediterranean spots. Except for Yumma's in the Inner Sunset. My wife and I stopped by yesterday and had one of the best, if not the best lunches we've had in our 6 years in San Francisco. Just *incredible*.
Everything was absolutely fresh and flavorful and *generous*. I had the mediterranean plate with falafel, goat cheese, baba ganouge, hummus, salad, and pita and it was fantastic! The falafel were crisp and perfectly seasoned, and the rest of the dish just rocked. My wife had the Nieman's Ranch lamb shawarma --a savory explosion unlike any shawarma I've had -- including the stand at the central bus station in Jerusalem. The lamb was tender, flavorful, not fatty and the balance of ingredients, wrapped in a pita roll, *perfectly* complemented the lamb flavors. Both plates were fantastic but the lamb shawarma is IMHO the most delicious lunch I've had in SF.
Prices are beyond fair -- around 5.50 for the mediterranean plate and 4.50 for the shawarma. On a nice day you can sit out on lovely back patio.
I saw one other review on CH from way back describing Yumma's as "okay". Based on our single lunch yesterday, I'd say this place is way, way, way, beyond okay and would choose either one of the dishes we had over most any high end restaurant dribble in San Francisco.
If you haven't tried it, try the shawarma and tell me if I'm off base here.
