I tried Sababa a few months ago.
I thought it was only okay, and I wouldn't exactly recommend it.
I ordered the Hummus Sampler & it was bland and tasteless to me.
My friends had a chicken wrap, which was decent, but nothing special.
The Greek Gourmet market, which also serves falafels and gyros across the street is even better. Some of the best hummus I've ever had. Fresh with tons of garlic. I recommend The Greek Gourmet. It's also ridiculously cheap
Stopped in for lunch and it was a terrible experience. I've never had such bland food in my life - no salt, no flavor. It must be what Israeli hospital food tastes like. I ordered the falafel sandwich and despite it being green with herbs, it had little flavor and was dry. My dining companion ordered a kebab which was also bland. The service was poor.
