Cafe
Iridescent
이리데센트 Iridesenteu Iridescent means shimmering and changing colour with the angle of view, like opal or a soap bubble — two posts say that is exactly what the name means to the house.

A café on the ground floor at Seoulsup 4-gil 20-1, between Seoul Forest and Ttukseom station. The draw is a citrus smoothie blended with perilla leaves (8,500 won): 15 of the 27 visits we counted ordered it. An americano is 5,000 won, the cream lattes 8,000 won, and the signature dessert is a tiramisu finished with ground pepper. Many posts say you order at the counter and staff bring drinks to your seat. We read 30 posts dated 24 May to 5 October 2026; 27 describe a visit, and 3 are roundup lists or magazine blurbs that we did not count.

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
- The front is a wall of glass that is folded open in good weather; nine posts mention it. One couple walked in off the street because they saw people chatting at the open windows. There is a window bar facing out, and two posts sat at the outdoor seats beside the entrance.
- Eleven posts call the staff kind, and most say why: drinks were brought to the table with an explanation of what is in them and how to eat them, staff suggested wrapping the smoothie in the perilla leaf (and hand out more leaves on request), and one dog owner was given water for her dog. The pepper on the tiramisu is also added by staff in front of you.
- Five posts say it is quiet enough to talk. Two describe a dark, black-toned room with music from large speakers. Seating is a window bar, a big communal table in the middle (one post says it seats up to about ten), two-tops further in, and sofas; three posts found the chairs or sofas comfortable.
- It fills up on weekends. Two posts waited: one says a queue kept forming, the other found it full at 2–3 pm on a weekend and came back after 6 pm. Two more got the last free seat, and one found plenty of room at 7 pm on a weekend but a full house by 8. No post gives a wait in minutes.
2 more
- Five posts walked there: one timed it at 7–8 minutes from Ttukseom station, another at 8 minutes from exit 8; Seoul Forest station exit 5 is about five minutes away.
- One post came with a dog: dogs are allowed only at the window seats, so if those are full you wait. Other posts list the café as pet-friendly, but only as copied listing info.

Where it 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

Getting inside
| In a basement | yes 0 · no 1 (of 21 posts read) |
|---|---|
| Toilet inside | yes 0 · no 2 (of 21 posts read) |
| Separate restrooms | 1 of 21 posts |
Only one post describes the floor from experience, calling it a black single-storey building; none mentions an upper floor or basement.
No one wrote from experience about a step at the door or getting in with a wheelchair or pushchair. Two posts copy a listing line saying the seats are wheelchair-accessible. Note too that the toilet is outside.
The toilet is not inside the café. Two posts say it is outside — one says you go out through a door by the kitchen; the other says it is separated by gender and fairly clean.
No one mentioned: Second floor · Lift to the floor · Ramp at the door · Step at the entrance · Step-free access · Accessible toilet. 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 24 posts we gathered, 3 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
- Sixteen posts give the same hours, daily 10:00 to 22:00, though most copy them from the listing. Holidays are disputed: one post's info block says closed on the day of Seollal and Chuseok, another says it stays open through the Chuseok holiday.
- Prices are consistent apart from the pepper tiramisu: 7,500 won in two June 2026 posts, 8,500 won in one July post. One post found prices a bit high, another called them good value for Seongsu. A drink and a dessert come to roughly 13,000–16,000 won.
- Eleven posts list the phone number 02-468-9438, all copied from the listing; nobody wrote about calling or booking. One post's info block says reservations are not taken.
- Six posts look written to a common template — the same 'worried the perilla would be too strong, but it was refreshing' arc, the 'original perilla smoothie' line and the Blue Ribbon mention, in the same order. None discloses sponsorship; one visit came through a reviewer platform. Claims about a hotel-trained barista, celebrity customers and fresh-squeezed fruit come from the shop, so we don't rely on them.
