Finding halal Chinese food is a challenge in SF, unless you go to Old Mandarin Islamic. At the Outer Sunset spot, the entire menu of Northern Chinese dishes is halal, and lamb is the show-stopping meat. It’s served folded into dumplings, in rib form, or stir-fried with water chestnuts, onion, and what tastes like a bucketload of cumin that fills the bare-bones space with a sweet-earthy fragrance. The group dinner move on grey nights is an order of noodles topped with smoky fried bean paste, hearty soups, and Beijing-style hot pot.
