I come here relatively often, and although the chicken used for shawarma is sometimes inconsistent in quality, the majority of the time it is decent and the mixed grill plate/anything freshly grilled for you is good and worth a try. The owners are extremely nice and friendly people if you take the time to speak to them and I don't know what everyone else is talking about in terms of asking for extra. They consistently give me extra pickles, turnips, and tahini for no extra charge. I think the issue is those customers that had these issues likely asked for them in a rude manner. You get a lot farther with a little bit of kindness. Keep in mind this is not a regular restaurant, but rather almost a kind of fast food place in which you quickly get your meal (and most often leave with takeout).
