Oilje’s July 2026 birthday table has already reached full reservation capacity, making the restaurant’s special birthday meal the clearest angle for anyone following Oilje Seaweed Soup this summer. The official Oilje account also noted that reservations for the August birthday table opened on July 1, 2026, at 5:00 p.m., and that birthday table bookings are accepted only through Catch Table. 1
That matters because Oilje is not a large, wide-ranging restaurant with many menu choices. Its identity is built around a single dish: perilla seed seaweed soup. The restaurant’s official information lists the menu as only 들깨미역국, or perilla seed seaweed soup, and gives weekday business hours of Monday through Friday, 10:00 to 15:00, with closures on Saturdays, Sundays, and public holidays. 2 The official address is 180-1 Hangangno 1-ga, Yongsan-gu, Seoul, which is useful to note because the available official information points to Yongsan near Samgakji Station rather than Jongno. 2
Oilje’s July Birthday Table Is Already Fully Booked

For July 2026, the key reservation fact is simple: the birthday table is closed because all slots are booked. 1 For readers trying to understand why this small event draws attention, the format helps explain the demand. The MICHELIN Guide describes Oilje as a Korean restaurant in Seoul and notes that it operates a special Friday evening birthday table prepared for guests celebrating birthdays. 3
Cook&Chef also reported that Oilje runs a birthday table course on Friday evenings for just one team each week. 4 In practical terms, that makes the experience very limited even before considering wider interest in the restaurant. A regular weekday lunch restaurant can serve more people across several days, but a once-a-week, one-team birthday setting naturally turns into a reservation race.
The birthday table also connects neatly with the meaning of seaweed soup in Korean food culture. The provided sources do not spell out a full cultural history, so it is better not to overstate it here. What can be said is that Oilje’s birthday service centers a dish already associated with a birthday meal, and the restaurant frames the Friday evening table specifically for birthday guests. 3
The Single-Dish Restaurant Behind the Demand
Oilje’s regular menu is focused on perilla seed seaweed soup, not a long list of stews, side dishes, or seasonal specials. 2 Cook&Chef described the restaurant as having one single menu item and identified key elements including young seaweed from Geogeumdo, Korean beef bone broth, perilla from Gangjin in South Jeolla Province, and Koshihikari rice cooked in a cauldron. 4
Chosun Ilbo reported similar details about the soup, noting that Oilje uses young seaweed from Geogeumdo in Goheung, South Jeolla Province, stir-fries it in perilla oil, and makes the soup with Korean beef bone broth. 5 Monthly Food Service Management described the preparation in operational terms: young Geogeumdo seaweed is used, Korean beef bone broth is boiled, aged and diluted, and each serving is cooked individually. 6
That narrow focus is part of the restaurant’s story. Monthly Food Service Management presented Oilje as a case of a single-menu restaurant designed around a one-person operating system, open five days a week for five hours a day and limited to 50 bowls. It also described the restaurant’s structure as 70% reservations and 30% walk-ins. 6 When a place already works with limited daily volume, the extra-limited Friday birthday table becomes even more distinctive.
The restaurant’s recognition has also added context. Cook&Chef reported on November 25, 2025, that Oilje was named in the MICHELIN Guide 2026 new selection. 4 The same report included a MICHELIN Guide description of the soup as having “a good balance of clear yet deep flavor.” 4 That short phrase fits the way the sources describe the dish: familiar in form, but carefully built through ingredient sourcing and broth preparation.
Why the Birthday Table Feels Like a Natural Extension
The birthday table does not appear separate from Oilje’s everyday identity. It seems to deepen the same idea: one bowl of seaweed soup, rice, and a focused Korean meal, prepared with enough care to become an occasion. The regular restaurant is already built around a dish many diners recognize, while the birthday table gives that dish a more ceremonial setting on Friday evenings. 3
There is also a broader audience around Oilje now. Chosun Ilbo reported on October 3, 2025, that the Yongsan restaurant had become popular with Japanese tourists, had been introduced several times in Japanese media, and was preparing for an Osaka pop-up. 5 Chef Shin Dong-hoon was quoted as saying, “I prepared the restaurant for various Korean age groups, but I never imagined there would be this many Japanese guests.” 5
That detail helps explain why reservation information gets attention beyond regular local dining notices. Oilje is a small restaurant with a highly specific menu, but the conversation around it includes MICHELIN attention, tourism interest, limited bowls, and a birthday course that only one team can experience on a Friday evening. None of those facts alone fully explains the popularity; together, they show why the July 2026 birthday table could fill up quickly.

For anyone keeping an eye on Oilje’s birthday meals, the most important current detail is that July 2026 reservations are fully booked, while the next August reservation round was scheduled to begin on July 1, 2026, at 5:00 p.m. through Catch Table only. 1 Oilje’s story remains tightly focused: a Yongsan restaurant, one perilla seed seaweed soup menu, weekday daytime service, and a Friday birthday table that turns a familiar Korean bowl into a limited celebration.
