Taking cues from the ever-popular Middle Eastern street foods from Mamnoon’s to-go menu up on Capitol Hill, owners Wassef and Racha Harouns have transported this quick-and-casual concept to the Amazon patch of Sixth Ave. The same small plate, or mezze, favorites are here such as the bright quinoa tabbouleh and (yes!) the spicy harra frites with Aleppo pepper, cayenne, and cilantro. A staple of Lebanese street food, their mana’eesh flatbread lineup can naturally be found here too. But folks cluster on the sidewalk for this: shawarma made with chicken or lamb accompanied by pickled turnips, herbs, and a special Mamnoon Street sauce, or pickled pepper and a roasted garlic sauce.
