Within the 610 loop : Best falafel?

I recently came back from vacation in Europe where I had the best darn falafel I've ever had. Roughly doughnut shaped, presumably so the center gets done while preserving moisture in the outer portions, it had a slightly crispy crust. Spiced very well. It was very good. Now falafel is not part of my usual food choices, but I've been dreaming of that falafel. I recognize that there are probably as many different recipes and implementations as there are grandmothers who pass down the recipes (for what it's worth the place was a Syrian restaurant but I don't know if that is representative of a Syrian way of cooking), but what places inside the loop have great falafel? (if it is just outside that is okay but I'm not driving that far so Katy is out but just north of the loop is good).

And please, no jokes about Salata's bone dry and not flavorful falafel that should be named Feel-Awful
