I wouldn’t say Tahini is in the “outer Mission” - it’s only a half block south of 24th Street BART.
In any case, I tried it tonight and thought it was quite good. The owner is a former techie of Lebanese/Syrian descent, and this is his first restaurant. We sampled most of the kebab varieties on offer and they were all nice and juicy. The lamb options had good, slightly gamy flavor. For the sides, we went with the “Lebanese” option and these did fit my understanding of the Lebanese hummus style - creamy and balanced. (I tend to prefer more lemony/garlicky styles, but this rendition seemed true to the advertised style.) Pita is made in house; I also liked the pickled turnip/cucumber on the sides platter.
Decent beer selection too. My one suggestion for the owner was that more kebap options would be great, though I realize that stuff like liver/sweetbread kebaps are a tough sell in SF. (I would also love another option for sabich in SF, but ain’t holding my breath despite falafel figuring prominently on the Tahini menu.)
