Duck Fat

덕펫 Deokpet “Duck Fat” — the fat rendered from a duck, and the foundation of south-west French cooking; the one dish that has never left the menu is a duck-breast steak. Korean signs and posts write it both 덕펫 and 덕팻

Duck Fat is a French tasting-menu restaurant in a basement off a Seoul Forest lane. There is one menu — the Duck Fat Course, ₩59,000, nine or ten dishes with an aperitif. Eight seats at an L-shaped counter, one party booked per time slot. The chef serves each plate across that counter and explains it, and eleven of the sixteen posts treat that explanation as the point of the place. Closed Tuesdays and Wednesdays. The posts we read run from December 2025 to June 2026.

The basics

8 posts say it is walkable from the station.

When it opens

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 people order

• DUCK FAT COURSE16 ate it
  Duck Fat Course₩59,000 · ₩69,000 · ₩76,000

  The only thing on the menu: nine or ten courses with an aperitif, served one plate at a time across the counter with an explanation of each. **About an hour and twenty minutes,** by two accounts

  **The price came down.** Two December 2025 posts put it at ₩76,000; from February 2026 the figure is ₩59,000, and six later posts mention the cut. One post from late March gives ₩69,000, but says it was bought as a two-person voucher. Drinks are extra

• 프렌치 어니언 스프15 ate it
  French onion soup

  **One of the two dishes that never change.** Stock boiled thirteen hours and onions caramelised for three, by several accounts; chicken and beef stock mixed, with Emmental and goat's cheese

  The hours quoted vary post to post — thirteen, sixteen, seventeen, twenty-four. **It draws more praise than anything else here:** the best onion soup one writer has eaten, better than in France for another, and enough to convert a friend who dislikes soup. Three advise saving a piece of baguette for it

• 오리 가슴살 스테이크15 ate it
  duck breast steak

  **The other constant, and the reason for the name.** Sous-vide then finished in a pan, with purple sweet potato and pea purées, an orange gastrique and balsamic. Three writers were told to eat the skin with it

  Five say it carries none of the usual duck smell; one says you would take it for beef. Two had never eaten duck this way. One notes the vegetables beside it are cooked in duck fat too

• 미트파이14 ate it
  meat pie

  The last of the mains — sixty per cent beef, twelve ingredients, two days to make, by these accounts, with sour cream alongside. Two writers were warned it comes straight from the oven

  One writer reports the whole table praising it; three name it their favourite; three liken it to a compressed beef bourguignon. Whether its origin is French or borrowed from a Japanese recipe, the posts disagree

• 식전주 — 와인비어 / 오디 에이드13 ate it
  aperitif

  Included, and **you choose between alcohol and none** — a beer aged in wine casks, or a mulberry cordial pressed in house. Two writers note it means a driver is not left out

  Four describe wine aroma and acidity over a beer's fizz; one tasted yoghurt instead. The two December posts had olives and walnuts with it

• 구제르 · 바게트 2종 · 이즈니 버터13 ate it
  gougère, baguette, Isigny butter

  The gougère is a Burgundian cheese puff of Gouda and Emmental; three writers reach for the same Korean snack to describe it. Two baguettes of different textures, and six posts say they come **from a bakery up the road**

  **The salted butter gets explained to everyone.** Five posts repeat the reasoning: a French course runs three hours and wants unsalted, this one runs eighty minutes and does not. Two add that the bakery has won a baguette championship

• 디저트 (티라미수 → 오페라 케이크)13 ate it
  dessert

  Tiramisu with organic maple syrup until April; an opera cake after. **Three writers were told to cut down through it and take every layer at once**

  In December 2025 the tiramisu was not part of the course at all but a gift to that month's bookings; the course ended with cheese instead

• 무화과 샐러드13 ate it
  fig salad

  **The salad comes after the main,** which is the French order, as several writers were told. Figs steeped a day in wine, with a blueberry — or cherry — dressing

  One records the dressing as ground blueberry and Dijon, made in house. One wished there were more of it

• 소르베 (레몬 → 라즈베리)13 ate it
  sorbet

  The palate cleanser between mains — lemon until April, raspberry after. **A mango jelly shaped like a duck sits on top,** and it is the most photographed thing in the place

  No dairy at all, and twenty-four hours of freezing and churning, by two accounts. Two taste a whole lemon in it. One writer took the duck for chocolate

• 연어 콩피 관자 리조또 (겨울~봄 시즌)12 ate it
  salmon confit and scallop risotto

  **The fish course until April 2026** — salmon cooked slowly in low-temperature oil over a scallop cream risotto, with a lotus-root crisp

  Two find barley mixed into the rice. One was told the rice is cooked past al dente because Koreans tend not to like it that way; another, that the salmon is left unseasoned because the risotto already is

• 캐비어 굴찜 (겨울~봄 시즌)10 ate it
  steamed oyster with caviar

  **A seasonal dish, gone after April 2026.** Oysters in the shell on a volcanic stone bowl, with a white sauce, basil, chopped shallot and caviar, cut to spoon size and served with a spoon

  Three writers who cannot normally eat oysters ate these; one says their friend's fear of them ended here. One was relieved they were steamed rather than raw. One asked for the sauce recipe

• 감자 파베 & 돼지 안심 스테이크 (여름 시즌)3 ate it
  potato pavé and pork tenderloin

  **Part of the course from May 2026.** A pavé is a paving stone; here, potato sliced thin, stacked in layers and fried, **with caviar on top.** The pork tenderloin comes with a gondre purée and blueberry compote

  All three note the sriracha mayonnaise, and the explanation that in France chips go with mayonnaise rather than ketchup. One was told the potato is sliced thin enough to see a hand through, over several days

• 치즈 플레터 (2025년 12월)3 ate it
  cheese plate

  **It appears only in the three December 2025 posts** — mild cheeses sliced thin, with the brie warmed and honeyed, and a berry yoghurt alongside

  One writer notes that the bread, the cheese and the tiramisu were the three things shared between two, rather than plated one each

• 대구 뫼니에르 (여름 시즌)3 ate it
  cod meunière

  **The fish course from May 2026** — the skin taken off a white fish and replaced with thin potato, crisped in its place, with a lime butter sauce and capers

  All three record a raspberry compote and a grape-mint jam beside it, to choose between

Parking

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

There is no car park. Four posts say parking here is hard and three recommend the train. One writer who drove leaves directions: a municipal car park by the Ttukseom retention basin, then a three-minute walk past the gardening centre, at ₩150 per five minutes — ₩1,800 an hour — with discounts for low-emission cars and large families. Another names a different municipal car park as the nearest.

Who came, and with whom

Getting there

Naver Map has a full English mode — Settings → Language → English. In Korea it gives better walking and transit directions than Google Maps.

Getting inside

It is a basement, down a flight of steps. Seven posts say basement and five of those describe the descent — the light dropping as you go down, a small entrance below street level, a half-basement. How many steps, and whether there is a lift or a ramp, nobody writes. Nor does anyone say whether a wheelchair or a pushchair gets in. That there are steps, five separate writers do say.

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 17 posts we gathered, 1 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.

When the posts appeared

What we do not know

• The whole course was replaced. The ten posts from before May 2026 ate steamed oyster with caviar, a salmon confit risotto, lemon sorbet and tiramisu. The three from May onward ate a potato pavé with pork, cod meunière, raspberry sorbet and an opera cake. Only the onion soup and the duck breast appear in both. Two writers were told two or three dishes change with the season, one that spring means potato and summer abalone, one that April would bring changes. So anything marked seasonal below may well be gone.
• The opening hours differ by date — they look to have changed. Five posts from December 2025 to March 2026 all give 17:00–22:00. Four from April onward give 10:00–22:00 on Monday, Thursday and Friday, 11:30–22:00 at weekends, with a break from 14:30 to 17:30. Lunch seems to have been added: a December writer notes that lunch then ran only at weekends and that a weekday version was being worked out. On Tuesdays and Wednesdays being closed, all eleven that mention it agree.
• One post is not an account of a visit, and we left it out. It calls the place dog-friendly, which none of the other sixteen mentions; it gets the bakery's name wrong; and instead of saying what was eaten it lists what might be — oyster in one season, octopus in another. It reads as a compilation of the other posts. One post does disclose sponsorship, though only in a hashtag at the very bottom. For what it is worth, the two posts published on the same day in December 2025 each embed the booking link five times and repeat a 'book for Christmas' line. Neither says it was paid for, and we have not counted them as such. They are, however, the two that record the ₩76,000 price.
• Not one of the sixteen mentions a toilet — inside or out in the building. That it is all one basement floor, several do say.
• Nobody writes about waiting, one way or the other. The place books one party per slot, so there is presumably nothing to queue for, and none of the sixteen mentions it. What they do mention is the slots filling: one says they go quickly, another that the year-end dates need booking ahead.
