In Yerushalayim I like the Falafel at Rav Shefa.
I also enjoy many of the CafeCafe locations for a nice milchig/parve meal.
Personally I don't find their falafel to be so great. I guess it's a matter of taste, so everyone will have a falafel place that he will prefer to go to...
CafeCafe rocks! They are located everywhere. I found one at some run down petrol station in the middle of nowhere. Always good to grab something to eat, but I still wouldn't rely on the name for good food as every place is very different.
