You’ll have to trek up to College Park to find food from Shanxi province, but this mouth-puckering cuisine is worth leaving DC for. Start with the black vinegar peanuts—toasted with skins on and drenched in a sweet, salty, and sour sauce. The sour soup dumplings, stuffed with spinach and punchy with black vinegar, feel both familiar and revelatory, while the Shanxi pork rib noodles feature hand-pulled noodles so thick they could double as jump ropes and pork ribs so tender they fall apart if you look at them wrong.
