Dim Dim Sum

딤딤섬 롯데월드몰점 Dimdimseom Lotte World Mall-jeom Dim Dim Sum doubles the word dim sum, the Cantonese small plates the house serves; the posts call it a Hong Kong dim sum chain.

Compiled from 20 blog posts read in fullSources →

A Hong Kong dim sum restaurant at the far end of the food court on basement level 1 of Lotte World Mall in Jamsil, on the aquarium side. Dim sum run 6,500 to 7,500 won a basket (xiaolongbao 6,500, har gow 7,500, siu mai and eggplant dim sum 7,000), and the crispy rice roll is 10,000. Groups order sets to share: 49,000 won for two, 72,000 for three, 105,000 for the three-to-four-person BBQ family set. We read 30 posts dated April 16 to October 22, 2026; 20 describe eating here. We set aside 8 that were about other restaurants in the mall and did not count 2 restaurant lists.

Counted from what bloggers wrote in their posts; we did not confirm it with the restaurant. Where the values differ, it may be a change over time rather than a disagreement, so we show when each one was written.

What sets it apart

  1. There is a wait, but rarely a long one. Of the 20 visit posts, 10 say they waited: 7, 10, 10, 10, 20, 30 and 30 minutes, plus one that was quoted 15. The 30-minute waits were a public-holiday lunch and a day the machine first quoted 42 minutes. One post walked in on a Friday at 6 pm in under 10 minutes. People sign up at the machine by the door or on CatchTable and browse the mall; 2 posts mention chairs or a waiting area inside.
  2. Three posts say the mall connects directly to Jamsil Station. Distances like '29 m from exit 10' are copied from the listing.
  3. The dish posts single out is the crispy rice roll: 10 ordered it and describe fried shrimp inside a soft rice sheet, 'crunchy but not jarring'. Counting the spring rolls, 11 posts called something here crisp.
  4. Sixteen posts ordered the xiaolongbao and 12 mention the broth inside. One found the skin slightly dry; another called it just okay.
6 more
  1. Anything with mala is hot. Nine posts call it spicy, about the mala wontons and mala noodle soups. The 2 that disagree were talking about the mala cucumber, which was milder than expected, and a family order with no mala dishes.
  2. The sets are generous: 6 posts say so, including four women full on the three-person set and three adults stuffed on the BBQ family set. One post says individual baskets are small enough to tempt you into ordering many.
  3. Five posts came with children, 2 of them using a high chair. The kids ate the egg-noodle wonton soup, har gow and char siu rice; families skipped the mala dishes.
  4. Adding the KakaoTalk channel gives a 2,000-won coupon, and 3 posts say they used it. The monthly 10% coupon is copied from the shop's own KakaoTalk notice.
  5. Four posts say it looks small from outside but seats run deep inside; 1 found the tables cramped. One notes most tables are for two, so larger groups may wait longer.
  6. Two posts ordered by the QR code on the table, and several say the food came out fast.

Parking

2 posts say you can park. None say you cannot.

Posts saying you can park2 of 20 posts

You can park in the mall garage, but several posts say eating here earns no parking discount. Two posts actually parked and gave figures, one paying about 8,600 won for three hours. One post's copied note says parking is validated, which contradicts the rest.

Where it is

Map showing where Dim Dim Sum is

We could not find this shop’s own listing on Naver Map, so the link searches for its Korean name around this spot instead.

From the station

Three posts say the mall connects directly to Jamsil Station. Distances like '29 m from exit 10' are copied from the listing.

Getting inside

In a basement6 of 20 posts
Step-free accessyes 0 · no 1 (of 20 posts read)

Six posts place it at the far end of the basement-1 food court (Sweet Salon 3355), near Muji. It is easy to miss: one post got lost by the Lotte Mart entrance, another says approach from the aquarium side.

We know little about getting in. One post says strollers are not allowed inside and had to be left by the door. Nobody mentioned a step at the entrance or wheelchair access; that means unknown, not absent.

We don't know about restrooms: no post says whether they are inside the restaurant or shared with the mall. Two posts copied 'separate men's and women's restrooms' from the listing, which we did not count.

No one mentioned: Second floor · Lift to the floor · Ramp at the door · Step at the entrance · Toilet inside · Accessible toilet · Separate restrooms. That is not the same as there being none — it means we could not confirm it. Worth calling ahead, and do tell us: we will put it here.

Posts that followed a TV spot

Of the 22 posts we gathered, 2 went up on a single day right after a TV spot and show no sign of a visit. They retell the broadcast, so we left them out of the counts.

We do not discard them. That a TV spot produced a burst of posts is itself something worth knowing about a place, and a star rating will not show it.

What we do not know

  • One post found a hair in the siu mai; the replacement was forgotten and nobody apologised at first, though the dish was taken off the bill. No post described the staff as friendly.
  • Opinions on salt split evenly: 2 posts found things salty (the rice-roll soy sauce, the roast duck glaze) and 2 said not.
  • Prices for individual dishes held steady from May to October (xiaolongbao 6,500, har gow 7,500, siu mai 7,000 won). Only the two-person set moved: 45,000 won in a post with a June 2026 receipt, 49,000 from late August. With a single post at the old price, we can only say it rose sometime between June and August.
  • Opening hours appear in 14 posts, 13 of them giving 10:30 to 22:00. Last orders split 10 to 2 between 21:00 and 21:30, and one June 2026 post alone lists 10:30 to 21:00 with last orders at 20:30. All are copied from the listing rather than observed. Three posts note a noon opening on Lunar New Year's Day and Chuseok.
  • Many posts copy the phone number, 0507-1348-2846, but none booked by phone; the wait list runs through the door machine or CatchTable. One post advises naming your preferred seat when reserving, without saying it reserved.
