I saw the recommendation for L’as du Falafel on David Lebovitz’ website (http://www.davidlebovitz.com/), which is actually where I got all of my paris recommendations. There was plenty of falafels that were nice and crispy and flavourful. The only problem is that it’s way too big. It’s as big as my face! Okay, not really but almost.
There are three falafel shops all claiming to be the best on Rue des Rosiers but the one that’s supposed to be famous and legit is L’As du Falafel. Their service is very efficient— you stand in line and give the order to one guy and pay for your food. Then, you give your ticket to one of the guys in the kitchen area where they’ll whip up a falafel for you SUPER QUICK.
