Seongsu Sushi Itchi Lunch Omakase: A 40-Minute Sushi Course in Seoul’s Seongsu-dong

Sushi Itchi Seongsu is drawing attention for a lunch omakase format that is compact, clearly priced, and easy to understand before you book. The lunch sushi omakase is listed as a 29,000 won course built around chef-selected sushi, a meal component, and dessert, with 12 items served over about 40 minutes.¹

For diners looking around Seongsu-dong for a focused sushi counter experience without a long meal commitment, that structure is the main appeal. The available source material points to a restaurant where lunch is designed as a concise omakase course, while the broader menu also includes dinner omakase and a separate weekend lunch format.²

What the Sushi Itchi Seongsu Lunch Omakase Includes

The core lunch course at Sushi Itchi Seongsu is described as a 12-item course including dessert, and the official site also presents it as a 40-minute lunch course.³ CatchTable’s reservation page gives the same essential shape: lunch sushi omakase at 29,000 won, with chef-selected sushi, a meal, and dessert included in the 12-part composition.¹

That matters because omakase can sometimes feel vague from the outside. Here, the known details are straightforward: this is not described as an open-ended tasting menu, but as a timed lunch course with a set item count. If you are comparing options in Seongsu, the clearest source-backed takeaway is that the weekday-style lunch course is relatively short, structured, and price-transparent.

The restaurant is listed in Seongsu-dong 1-ga as a Japanese dining spot, with lunch omakase and dinner omakase shown as representative menu items on Naver Place’s “Seoul Matdongyeojido” eastern Seoul page.⁴ Polle also lists the venue as Sushi Itchi Seongsu in Seongsu-dong 1-ga, with the address shown as 1F, Metamorpho, 89 Seongsuil-ro, Seongdong-gu, Seoul.²

Menu information from Polle lines up with the main lunch pricing shown elsewhere: lunch sushi omakase is listed at 29,000 won, dinner sushi omakase at 39,000 won, and weekend lunch sushi omakase at 39,000 won.² The official site adds more detail for weekends, describing weekend lunch as a 15-item course including dessert, served over 70 minutes, with two seatings at 11:30 and 13:00.³

Booking, Timing, and the Weekend Difference

A useful thing to know before planning around Sushi Itchi Seongsu is that reservations are not presented as casual walk-in arrangements in the official guidance. The official site says reservations are taken through a reservation platform with prepayment.³ CatchTable’s Sushi Itchi Seongsu page is one of the source-backed reservation references, and it displays the lunch sushi omakase menu at 29,000 won.¹

The weekday-style lunch course and weekend lunch course should not be treated as identical. The lunch course described on the official site is 12 items including dessert and takes 40 minutes, while the weekend lunch is described as 15 items including dessert and takes 70 minutes.³ Polle’s menu summary also separates lunch sushi omakase at 29,000 won from weekend lunch sushi omakase at 39,000 won.²

That difference is helpful if you are deciding when to reserve. A 40-minute course can fit a tighter lunch window, while the weekend version appears to be a longer meal with more items. The source material does not provide a full item-by-item official menu for every course, so it is safest to treat the item count, timing, and prices as the firm details rather than assuming exactly what will be served on a specific day.

There is also a promotional note connected to Naver Reservation’s “Seoul Matdongyeojido: Seongsu and Konkuk University Entrance” selection. Sushi Itchi Seongsu’s official Instagram post announced that selection and said a 20% discount coupon could be applied through Naver Reservation, showing the lunch price for two people changing from 58,000 won to 48,000 won.⁵ Because the provided source does not include an end date, readers should check the reservation page directly before relying on that discount for a specific booking.

Atmosphere and Menu Clues from Dining Listings

Beyond the official course structure, dining platforms give a little more context about what the experience may feel like. Siksin describes the lunch omakase as a 40-minute course and summarizes highlights including a mostly counter-seat setup, 12 seats, and a quiet atmosphere.⁶ Its AI-highlighted menu experience mentions items such as squid sushi, scallop temaki, futomaki, shrimp tempura, and yuzu sorbet.⁶

Those details should be read carefully. They are useful as dining-listing context, not as a guaranteed current menu for every reservation. Omakase menus can vary, and the more dependable fixed facts in the source material are the course length, item count, pricing, reservation style, and representative menu categories.

Still, the overall picture is consistent: Sushi Itchi Seongsu is positioned around sushi omakase in a small-format setting, with lunch as the most accessible entry point. Naver’s listing of the restaurant as part of the eastern Seoul “Matdongyeojido” selection also places it within a broader Seongsu and Konkuk University Entrance dining map, where lunch and dinner omakase are the representative menu items.⁴
