Sushi Seki is a Thai-run sushi chain (no relation to the New York restaurant of the same name) that has built a loyal following across Bangkok's malls, with around nine branches including Siam Paragon, Central World, MegaBangna, and Central Ladprao. The EmQuartier outpost on the 4th floor is one of the more compact rooms in the group, seating roughly 20 people along a minimalist wood counter.
The format is accessible omakase paired with a full a la carte menu of nigiri, sashimi, and signature rolls. Seafood is flown in from Japan, and the chefs work through the day's supply in front of you, which is why regulars tend to sit at the counter rather than the small table section. Check prices are noticeably lower than the standalone omakase bars around Sukhumvit, which is the point of the concept. One thing to note before you plan a long dinner: Sushi Seki does not serve alcohol at any of its branches.
You step off the EmQuartier escalator on 4 and find a narrow, pale-wood counter with a glass case of the day's fish. Service is quick and warm rather than ceremonial, closer in feel to a neighborhood sushi-ya than a hushed chef's-table room. Most tables turn within an hour, and walk-ins at odd hours are usually fine even though weekends and the 7 to 9 pm window fill up.
You order one of the omakase sets if you want the chef to steer, or you build a meal a la carte from the printed menu. The crowd skews local: Thai regulars from the surrounding offices and condos, couples before a movie upstairs, families sharing platters. No wine list, no sake flight, just green tea and soft drinks, which keeps the bill and the pace in check.
The Omakase Set is how most first-timers go, a chef's selection built around whatever arrived from Japan that morning and usually running through a sequence of nigiri, a sashimi course, and a warm item or two. Toro nigiri is the dish regulars order on repeat, cut thick and brushed lightly with soy at the counter. Beyond the raw fish, Sushi Seki leans into its signature rolls, maki that bend traditional technique toward modern flavors and show up on almost every table in the room. Rounding things out is the straight a la carte list of nigiri and sashimi pieces, which is where the kitchen's access to Japan-imported seafood pays off without committing to a full tasting.
Sushi Seki sits on the 4th floor of EmQuartier, the Helix side of the mall above the Sukhumvit and Soi 24 junction. It's a two-minute walk from BTS Phrom Phong exit 1 via the covered skybridge, which makes it one of the easier sushi restaurants in Phrom Phong, Bangkok to reach without a car.
