Kokkili Bagel Seongsu is best understood through its waiting line: multiple Korean reports describe a Seongsu bagel shop popular enough to draw queues outside the store and sell out key menu items by around lunchtime. For anyone planning a visit, the main thing to know is simple but important: the waiting situation can vary, yet the shop’s reputation was built around strong demand, wood-fired bagels, and limited direct-run locations rather than rapid chain expansion. 1
The Seongsu branch belongs to Kokkili Bagel, a brand that began with its first shop in Yangpyeong-dong, Yeongdeungpo-gu in 2017 and later expanded to Yongsan and Seongsu, making three directly operated stores in total. 1 The Seongsu location opened in October 2022, and it has been described as both a major sales driver and a place for testing new menu ideas. 2
Kokkili Bagel Seongsu Waiting: Why the Line Became Part of the Story

The waiting issue at Kokkili Bagel Seongsu is not just a small footnote. Maeil Business Newspaper described the Seongsu shop as a bagel store people line up for, and during the reporter’s visit, the line for buying bagels was long. By around lunchtime, popular items such as plain bagels and cream cheese bagels had already sold out. 3
That detail matters because it gives you a practical sense of the shop’s rhythm. The sources do not provide a fixed waiting-time chart, reservation rule, or guaranteed sellout hour. What they do show is that demand has been strong enough for queues and lunchtime sellouts to become part of the published coverage. If you are trying to avoid disappointment, the source-backed lesson is not “arrive at one exact minute,” but rather that later visits may bring fewer menu choices, especially for popular items. 3
The Seongsu branch has also been framed as the largest Kokkili Bagel store. Maeil Business Newspaper described it as a two-floor standalone location and reported monthly sales in the range of roughly 250 million to 300 million won. 3 Dong-A Ilbo separately reported Seongsu monthly sales of about 300 million won and said each store sold around 1,500 bagels per day on average. 2 Those numbers help explain why the line is such a visible part of the experience: this is not a quiet neighborhood bakery that suddenly appeared in a few social posts, but a high-volume shop with sustained attention.
What Makes the Bagels Different
The core distinction repeated in the coverage is the oven. Kokkili Bagel presents itself around wood-fired, or fire-oven, bagels rather than a standard electric-oven approach. In one interview, CEO Cheon Hong-won said, “The biggest feature is baking bagels in a fire oven, not an electric oven.” 3
That point is useful for readers because it explains why the waiting line is tied to production style, not only trendiness. The brand’s identity centers on bagels baked in a fire oven, and the company has described direct operation as another key part of how it maintains quality. The Economist’s interview at the Seongsu store reported that Kokkili Bagel emphasizes fire-oven bagels and directly operated stores as its main differentiators. 1
The brand has also been cautious about expansion. Cheon Hong-won told The Economist, “To focus on taste, we are trying not to increase the number of stores too rapidly.” 1 For customers, that can make the waiting feel more understandable: when a popular food brand chooses not to multiply locations quickly, demand stays concentrated at the few stores that exist.
There is also evidence that Kokkili Bagel’s popularity travels beyond its own storefronts. Korea Financial News reported that CJ Freshway sold seven popular Kokkili Bagel menu items at client in-house cafes from September 13 to 27, 2023, including plain, butter salt, and cream cheese whipped cream varieties made and supplied on the same day. The first day drew a long purchasing line, and total sales reached more than 3,000 items. 4 This does not describe the Seongsu store’s daily waiting pattern, but it does reinforce that the brand’s demand was not limited to one street corner.
Visiting Details You Can Actually Use
For location planning, NOL World lists Kokkili Bagel Seongsu as a wood-fired bagel shop in the Seongsu area, with the address given as 17, Seongsui-ro 26-gil, Seongdong-gu, Seoul. The place page also provides a phone number and official Instagram link, though it does not include waiting-time statistics or sellout data. 5
A 2025 personal blog visit report adds a softer, more situational note: during a weekday lunch visit, seats were available and the writer could sit down right away, while the post also cautioned that some items may sell out later in the day and that weekend waiting may occur. 6 Because that is a personal visit account rather than an official schedule or broad dataset, it is best read as a helpful snapshot, not a promise.
So, what should you take from the available facts? First, Kokkili Bagel Seongsu has enough documented popularity that waiting is a realistic possibility, especially when demand peaks. Second, sellouts have been reported by around lunchtime for certain popular menu items. Third, weekday conditions may be calmer at times, but the sources do not support a universal no-wait rule. If your priority is selection, earlier is safer than later based on the published sellout reports. 3

Bottom Line
Kokkili Bagel Seongsu’s waiting line is part of a bigger story: a wood-fired bagel brand that began in 2017, expanded carefully into three direct-run shops, and turned its Seongsu branch into a high-demand destination. If you are planning around Kokkili Bagel Seongsu, the most source-backed advice is to expect possible queues, understand that popular items can sell out, and check the location details before you go.
