OFFEN

오펜 커피 Open Keopi A small owner-run cafe by the Chungbuk National University gate, known for kaymak, cakes and a filter coffee that changes bean every month

Data as of 2026-09-27 · Published 2026-10-01 · Compiled by Gilpost

OFFEN is a small owner-run café on the main road between the front and middle gates of Chungbuk National University. The sign and the Instagram use the Latin name; the registered one is 오펜 커피. One man makes the coffee, including a filter coffee whose bean changes every month, and on the sweet side the place is known for kaymak and its cakes. Plants, no two tables alike, a chalkboard menu in the owner's hand — nearly every post reaches first for the word atmosphere. Beer and whisky appear at night. It opens at noon and closes on Wednesdays. The posts we read run from 1 October 2024 to 14 September 2026.

The basics

When it opens

Of 16 posts: 9 wrote Daily 12:00–22:00, 2 wrote Weekdays 10:00–22:00.

The values differ, but the periods they were written in do not overlap. This looks like a change over time rather than a disagreement, and the top row is the most recently reported. We did not confirm it with the restaurant.

These hours are counted from the posts we read. Shops change them without notice — check Naver Place before you go. Place — check hours

What people order

The most ordered dish is kaymak & baguette (카이막 & 바게트) — 9 of 22 posts.

The prices here are what bloggers wrote down in their posts, and they may have changed since. Check Naver Place for the current menu and prices. This list is not a menu board — it counts what bloggers actually ordered and ate. Check on Naver Place

Sweet things

• 카이막 & 바게트9 ate it
  kaymak & baguette₩9,000

  The house signature — the shop's own Instagram handle carries the word. Turkish clotted cream with a crisped baguette, and **a pool of honey underneath.** What comes alongside changes: cacao nibs in one account, chocolate chips in another, Häagen-Dazs with blueberry compote, grilled banana and fruit, brown cheese.

  One writer finds the milk flavour deep; another is glad it is not strong, and places it somewhere between cream cheese and Greek yoghurt. One calls the portion generous for the money; one gives it 3.5 out of 5 and says it is good rather than astonishing. On a day it came under cacao nibs, a writer with bad teeth ate carefully. **One came for it, was too full, and returned another day; four write that they still have not tried it.**

• 에그타르트5 ate it
  egg tart₩2,800

  **One of the two things the shop gives for writing a review**, so more people here were handed it than paid for it. Go at opening and the baking is not out yet, one writer notes.

  One writer rates the shop for these particularly and tells readers to claim theirs. Nobody describes the taste at length.

• 밤 바스크 치즈 케이크5 ate it
  bam basque cheesecake₩7,000

  Chestnut pieces under the cheesecake, soft white cream over it, with crushed Lotus biscuit and cacao nibs scattered on top by one account. One writer was told it is the owner's own favourite.

  One writer expected the dense basque style and found it soft throughout; another, who does not care for cheesecake, liked it for not being sweet. One says that asked what to eat here, the answer is this and nothing else. **It sells out of the case** — one writer stood in front of an empty shelf until the owner said there were more in the back.

• 휘낭시에5 ate it
  financier₩2,800

  The other half of the review giveaway. One long-standing customer remembers when they were baked thin and long and sold as a set with the einspänner.

  Crisp outside, buttery in, and as good as a specialist's, says one who has eaten a few. Another dipped hers in the pistachio cream.

• 마틸다 케이크3 ate it
  matilda cake₩8,000

  Modelled on the chocolate cake from the film Matilda, the one the headmistress makes the boy finish. Chocolate sponge, chocolate cream between the layers, a thick chocolate coat over the outside; one writer finds hazelnut in it.

  Two writers note the shop's own description calls it sweet-and-salty, and say the salt does hold up the chocolate. Three say it is less sweet than it looks and does not cloy by the end. **One slice is large enough for two to share**, according to one.

• 오펜 케이크 (자몽 얼그레이)2 ate it
  jamong earl grey cake₩9,000

  The cake that carries the shop's name. One account lists a mango version at the same price; in winter it turns up as strawberry and cream.

  Two writers ordered it and recommend it. Neither says much about how it tastes.

• 딸기 케이크 (겨울 한정)1 ate it
  strawberry cake

  **Winter only.** No post records the price.

  **Come late and it is gone** — the one writer who has it went in November, saw how few were left and was glad she had hurried; she had eaten the same cake the winter before. Hers is the only post that mentions it.

• 시나몬롤 & 크림named in 2
  cinnamon roll & cream₩4,800

  Two writers noted it in the case.

  **Not one post says they ate it.** Only the price survives: ₩4,800 in an August 2025 post.

To drink

• 아메리카노8 ate it
  americano₩5,000 · ₩5,500

  The most ordered drink here. **Decaf is available for five hundred won more.**

  Two describe it as nutty without acidity; another as dark and easy to like. The one who took it decaf was surprised how good it was. ₩5,000 in an April 2026 post; the decaf ₩5,500 in one from September 2025.

• 바질 토마토 에이드3 ate it
  basil tomato ade₩6,000

  A star beside it on the board, by one account — the drink people who do not take coffee tend to land on.

  **Stir it first** — one writer drank straight down and got nothing but basil, then found it good once mixed. If you dislike basil, she says, skip it. Another has had it in a good many cafés and rates this one first; another finds it on the sweet side.

• 필터 커피 (월간 브루잉)3 ate it
  filter coffee₩7,000

  Slow-poured through a dripper, and **the bean changes every month.** The shop says it buys from roasteries the owner picks himself. Every post names a different one: a Kenyan, a washed Huehuetenango from Guatemala, a Colombian gesha. One writer had three to choose from.

  Two copy down the tasting notes the shop puts up — black tea, grapefruit, brown sugar and apple for the Kenyan; peach, guava and honey for the gesha — and one of them adds that the owner simply brews it well. One ordered it iced in summer, knowing hot would show it better.

• 히비스커스 오렌지 주스3 ate it
  hibiscus orange juice

  It comes in layers, and **stirred together it turns the red of watermelon juice**, according to one writer.

  Tart but not sour, and sweeter than expected, say two. One who ordered it alongside the basil tomato preferred this one. Nobody writes down the price.

• 크림 커피 (피스타치오)2 ate it
  pistachio cream latte₩6,000

  Marked as a signature on the board, by one account: a latte under a cap of pistachio cream.

  One writer calls the balance of cream to coffee the best she has met; the pistachio, she says, is not the ice-cream-parlour kind but something nuttier that sits well in the milk. **Someone who does not much like pistachio ordered it and came away calling it the least divisive version she had tried.**

• 말차 라떼2 ate it
  matcha latte₩5,500

  Ordered hot, it arrives with a heart poured into it, one writer notes.

  One writer puts it first among the drinks.

• 오렌지 자몽 블랙티2 ate it
  orange jamong black tea

  Another one for the people who cannot take coffee. No post records the price.

  **A writer who cannot drink caffeine, and has therefore worked through the tea list of most cafés she enters, calls this one of the best she has had.** Orange sweetness at the front, she says, and the clean bitterness of the tea at the back; another finds it bright with the tea kept low.

• 오펜슈페너 (아인슈페너)1 ate it
  offen-spänner

  The einspänner under the shop's own name. One long-time customer remembers it sold as a set with a financier. No post gives a price.

  Only one post has it on the table, and that account is second-hand — the friend who drank it said it was very good. Two posts put it in their titles, and both ordered something else that day.

Parking

1 posts say you can park; 10 say you cannot. We leave the disagreement standing rather than picking a side.

Bring a car and parking is a real problem — one writer was fined. There is no car park. The kerb on the university side is tolerated, but only at certain hours: half eleven to two on weekdays by one account; at lunchtime and then freely after eight in the evening by another. One writer parked a little further up, got a ticket and paid close to forty thousand won, and now tells readers to use the back lane unless they can be gone by two. The opposite side, posts say, is patrolled all day. Several name the Sachang-dong community centre car park and the alley behind as the alternatives; one adds that the kerb is always full anyway.

Who came, and with whom

Getting there

Getting inside

Four posts say ground floor; the other twenty-one say nothing about floors at all. No one mentions stairs, a basement or an upstairs. The registered address gives part of the ground floor, and one writer notes the full-height window onto the main road, so you can see in from the pavement.

Not one post mentions a step, a ramp or a wheelchair. Whether there is a lip at the door, how wide it is, whether a pushchair fits — none of the twenty-five say. That is not "there is none"; it is nobody looked. What they give instead is that the room is small and on the ground floor, and nothing at all about the gaps between tables. Two posts say pets are welcome, but both are copying the facilities list off the shop's map entry, and no writer describes seeing a dog or a cat inside.

You can reach the toilet from inside, and that is the whole of what we know. Three posts touch on it: one says there is an indoor toilet straight through a connecting door, one simply notes that there is one, and one places the stamp-card box by the toilet door. Nobody says from their own eyes whether it is shared or separate — one post has "no separate men's and women's" in its header list, but that list is lifted wholesale from the map entry (wi-fi, booking and groups sit on the same line), so we have not counted it. Nothing about its size or state either.

No one mentioned: In a basement · Lift to the floor · Ramp at the door · Step at the entrance · Step-free access · 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 27 posts we gathered, 5 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 opening hours are the least trustworthy thing we can tell you about this place. They have moved repeatedly over two years and the posts still disagree. Spring 2025 has it closing at nine; August and September 2025 have it opening at ten in the morning, with different weekend hours; from November 2025 through the summer of 2026 it is noon to ten. Then a post from 5 September 2026 says noon to nine, last order 20:30, and one from nine days later says noon to ten. A March 2026 post says eleven at night, which its own last order of 21:30 contradicts. The shop itself tells people to check Instagram — two posts pass on that instruction, one noting the closures are irregular. And one writer walked to a locked door the day the owner had a cold. Twelve posts give Wednesday as the closing day; exactly one says the opposite, that it opens every day.
• Not one of the twenty-five writers came by bus. None names a stop, a route or a journey time. What they give instead are walking directions from the campus: between the front gate and the middle gate; down the steps by the international office, across one crossing and straight on towards the front gate; five minutes from the pork-cutlet place. There is plenty about walking and nothing about public transport, so whether you can get here on a bus is not something we can answer.
• Only four posts write down a price. Twenty-one of the twenty-five say what they ate and not what it cost. The four span August and September 2025 and April and May 2026, and nothing moved between them — the chestnut basque is ₩7,000 both times, the Matilda cake ₩8,000 both times, the kaymak ₩9,000 both times. Four is still four. Nobody calls the place expensive; three call it fair for a university street or good value for the size of the portion. One looked at the cake prices, thought them steep, and changed her mind when the slice arrived.
• Twenty-five, not thirty. Five posts came out. Two are round-ups of a dozen or more places near the campus, where OFFEN gets its opening hours and a recommended drink and nothing else. One is a machine-assembled page that copies the shop's own map blurb, its facilities list and its review-keyword tallies ("good coffee: rated by 349 reviewers"), with the opening-hours field left reading "no information". One is a diary that checks in and never says a word about the place. And one is a writer who walked up to a closed door the day the owner had a cold. Not a single post declares a sponsorship. Six say they paid their own way, one says a friend paid, and the remaining eighteen say nothing either way — which is not the same as saying there was nothing. The shop does run its own review-for-a-pastry offer, and that is set out above.
• The menu moves, so what you read here may not be there. Two writers note that the owner keeps changing things — the drinks, and the room itself. The filter coffee's bean changes monthly; the strawberry cake is winter only and the melon ade summer only. One long-standing customer remembers when the financiers were baked long and thin and sold with the einspänner, and early 2026 brought a Dubai-chocolate version of the Matilda cake. What sells, sells out — one writer found the cake shelf bare until the owner said there were more in the back, another hurried in for the last of the winter strawberry cakes, and a third arrived at opening to find the baking not yet out.
• Not one post describes queueing. In twenty-five accounts nobody waits, and nobody mentions a line. What they describe instead is getting a seat: customers coming in steadily, so you would have to arrive at opening to choose where you sit; the room filling in a moment; a fair few people already there. One found the place empty in the afternoon and busy by evening; another, on a weekday afternoon, had it quiet to herself. The single outdoor table is the one seat you do have to claim first. So we can tell you nothing about waiting, only about whether there is somewhere to sit.
