The aptly named L'As Du Fallafel ("the Ace of Falafel") is situated in the heart of the historically Jewish Marais neighborhood of Paris, a cobblestone landscape freckled by a dizzying number of falafel stands and kosher butchers. Among these, L'As is something of a legend owing almost entirely to its one-of-a-kind falafel sandwich, which includes grilled eggplant, cabbage, hummus, tahini, and hot sauce. Indeed, L'As falafel is renowned even in Israel. Take-out is the preferred modus operandi of locals and regulars, though dining-in (the atmosphere is lively, bordering on frenzied during peak lunch hours) makes for a slightly less messy experience. Still, this sandwich is so good you'll be happy to stroll down Rue des Rosiers, soaking in the atmosphere and sunshine, with hummus dripping down your chin.
