Cheolsanjang, Mullae: In Seoul's Steel District, the Broth Never Lets You Down

I have an old restaurant theory.

"In neighborhoods that work with iron, the broth is always good."

People who spend their day around molten metal and machine oil want a hearty, hot bowl, and a cold one that cools them right down. A restaurant in that kind of neighborhood can't survive on lazy broth. Mullae-dong, famous for its metalworking alleys, and Cheolsanjang, a restaurant with cheol (鐵, iron) right in its name, proved the theory perfectly.

A 30-second glossary

• Naengmyeon — cold noodles. Two classic styles below.
• Pyongyang naengmyeon — buckwheat noodles in a clear, chilled meat broth, named for the North Korean capital. Famously subtle.
• Bibim naengmyeon — buckwheat noodles tossed in a sweet-spicy red sauce instead of broth.
• Suyuk — boiled meat, thinly sliced. Here it's satae, beef shank.
• Mandu — dumplings. The Pyongyang style runs big.
• Cheol (철) — iron. A fitting name in Mullae-dong, a neighborhood of metalworking shops.

Bowl #1: Pyongyang naengmyeon

Clear broth sloshes in a stainless-steel bowl. On top: buckwheat noodles, sliced meat, a soft-boiled egg, cucumber. People say the first sip of Pyongyang naengmyeon tastes bland. But by the second and third, the deep flavor of the meat broth creeps up on you. The noodles have that short, snappy bite that only buckwheat gives you.

New to Pyongyang naengmyeon? Remember just one thing: hold off on the vinegar and mustard, and take three sips of broth first.

Bowl #2: bibim naengmyeon

If Pyongyang naengmyeon is the far end of subtle, bibim naengmyeon is the opposite end. A soft-boiled egg and sesame seeds sit on a bright red sauce. The sweet-spicy sauce clings to the buckwheat noodles, and if you alternate, one bite of Pyongyang, one bite of bibim, you're stuck in an endless spicy-then-cool loop. Going as two? Order one of each and share. That's the correct answer.

Plate #3: suyuk and mandu

A naengmyeon house shows its real skill in the side dishes, because a place that makes broth is, in the end, a place that boils meat. The suyuk comes thinly sliced, tender and moist, and it's great alternated with sips of the cold broth. The big Pyongyang mandu are packed full, and you can order a half plate (₩6,000), so they're an easy add-on.

Pyongyang naengmyeon, bibim naengmyeon, suyuk, mandu. Of everything on the table that day, there wasn't a single miss.

Naver Place's one-line summary reads, roughly, "a harmonious meeting of mulgalbi and naengmyeon" (mulgalbi being galbi cooked in broth). In other words, the meat dishes, like the pork galbi and the gopchang hot pot, have a following of their own. They went straight onto my list for next time.

How to order (even with zero Korean)

• Say "Pyongyang naengmyeon hana, bibim naengmyeon hana juseyo" (평양냉면 하나, 비빔냉면 하나 주세요) — one of each, please. The perfect order for two.
• Hungry? Add "Yang mani juseyo" (양 많이 주세요) — a bigger portion, please. Extra noodles cost nothing.
• For a side, ask for a half plate: "Suyuk ban jeopsi juseyo" (수육 반 접시 주세요) for half a plate of suyuk, or swap in mandu for dumplings.
• When the naengmyeon arrives: three sips of broth before you touch the vinegar and mustard.
