Jang Mo Jib’s downtown location is popular with ESL students looking to soak up the night’s drinking with rib-sticking Korean fare. Every country has its dumplings, and goon mahn doo, pan-fried and filled with ground pork and scallions, are Korea’s. Jab che is a delicious tangle of translucent sweet-potato noodles seasoned with sesame and tossed with shiitake mushrooms, julienned carrots, spinach, and thinly sliced beef. For a starch fix, dol sot bee bim bahb is a spicy jumble of preserved vegetables, beef, a fried egg, and house-made hot chili paste on steamed rice that crisps in a hot stone bowl.
