Seoul summers are brutal, and few things fix that faster than a bowl of icy cold noodles. If you’re shopping or sightseeing in Jamsil, the naengmyeon at Lotte World Mall worth stopping for is Seorae, on the 5th-floor restaurant level — thin chewy noodles, broth cold enough to have ice crystals in it, and the kind of place families pile into on a hot afternoon.
First: what kind of naengmyeon is this?
Naengmyeon is Korean cold noodles, and there are two main schools worth knowing:
- Pyongyang-style — thicker buckwheat noodles in a mild, subtle broth
- Hamhung-style — thin, springy, very chewy noodles, usually served with a sweet-spicy sauce
Seorae is a Hamhung-style specialist, making its broth in-house. If you like noodles with real bite, this is your camp — the strands here are notably fine and bouncy.
You’ll find it on the 5th-floor restaurant level, right next to Knotted. The dining room is big with lots of tables, so even when there’s a queue it moves fast.
What to order
Mul-naengmyeon (13,000 KRW) — the classic cold one
Cold noodles in chilled broth, served so cold there’s a thin slush of ice on the surface. The broth is deep and clean, and the noodles — made in house — are wonderfully chewy. On a hot day it genuinely resets you.
Hoe-naengmyeon (14,000 KRW) — the spicy mixed one
This is the sauce-mixed version, topped with hoe. A quick clarification, because the English menu just says “Spicy Noodles with Raw Fish”: this isn’t sashimi. Korean hoe here means seasoned or cured fish — typically pollack, skate, or ray — tossed in seasoning until firm and tangy rather than served as delicate raw slices. It adds a chewy, savory-tart depth you don’t get from the plain mixed version.
The sauce is sweet-spicy rather than fiery. Korean diners would call it mild — but if you’re not used to Korean chili, expect a real kick. Wrap a piece of the fish in noodles for the best bite.
Mandu (10,000 KRW) — order these too
Dumplings a little smaller than a baseball, packed full and juicy, with no gaminess in the pork. Noodles alone can feel light; a plate of mandu alongside makes it a proper meal. Naengmyeon and mandu is a classic Korean pairing for a reason.
Visiting in winter? Galbitang (18,000 KRW)
The menu isn’t only cold food — there’s galbitang, gukbap, tteok-mandu-guk, and more. The galbitang (short-rib soup) is worth knowing about if you’re here in colder months: like the naengmyeon broth, it’s genuinely good — clean and savory rather than greasy.
How to eat it like a local
There’s vinegar and mustard on every table — they’re there for the naengmyeon. A splash of vinegar sharpens the broth, and a little mustard adds warmth. Start with a small amount and adjust.
The complimentary side dishes — radish salad, kkakdugi, kimchi — are cold and crisp, and they pair perfectly with the noodles.
Details & tips
- Location: 5F, Lotte World Mall, 300 Olympic-ro, Songpa-gu — next to Knotted (Google Maps)
- Hours: 10:30am–10:00pm daily (last order 9:00pm)
- Ordering: staff take your order at the table. The menu lists dish names in English but has no photos — if you want to see what you’re ordering, check the restaurant’s Naver Map listing first. Cards accepted.
- Waiting: no reservation or waiting app — you queue at the door, and there’s a waiting bench. On a Saturday at 7pm there were about five groups ahead of us, but with a room this size the line clears quickly.

Verdict
For the best naengmyeon at Lotte World Mall, Seorae delivers exactly what a Seoul summer calls for: fine, chewy Hamhung-style noodles, broth with ice still in it, and dumplings on the side. Add vinegar, mix it up, and cool down properly — then head back out into the heat.
