"Chinese sandwiches get top billing at Xi’an Cuisine, which also operates a Chinatown location. Constructed from fresh flatbreads stuffed with savory marinated pork and cumin lamb, they’re a delightful on-ramp for newcomers to the street food of China’s northern region. Other favorites include chewy biangbiang noodles and lamb soup." - Ashok Selvam, Naomi Waxman
