Khao-Soi Soi Convent Silom is a modern northern Thai noodle shop that transplanted its Chiang Mai khao soi concept to Convent Road in October 2023. The menu runs on a single idea executed two ways: the house coconut-curry broth served over egg noodles in the classic soup, or stir-fried yakisoba-style in a dry preparation that tosses those same noodles with a secret sauce. Premium protein upgrades push it past the usual khao soi shop, with Iwate Wagyu F1 torched tableside, scallops, lobster, and braised pork all on offer.
The room on Convent Road is compact and the kitchen keeps the lineup tight, which is how Khao-Soi Soi has pulled a 4.8 average across more than 4,200 Google reviews since opening. Think of it as a northern Thai restaurant in Silom, Bangkok built around one dish done obsessively, with Japanese noodle technique and premium ingredient thinking layered on top.
You order at the table from a menu organized around two columns: broth khao soi on one side, dried khao soi on the other, with protein upgrades listed alongside. Service is quick and functional, closer to a specialist noodle shop than a sit-down dinner, and turnover is steady through the 10:30 AM to 9:00 PM run. If you go for the Iwate Wagyu version, the slices arrive raw and get finished tableside with a blowtorch before going onto the noodles. Crowds skew toward Silom office workers at lunch and a mix of locals and visitors in the evening.
The dish to order first is the Iwate Wagyu F1 Khao Soi, wagyu slices torched tableside over springy egg noodles in the house coconut-curry broth, finished with a spoonful of fish roe. The Dried Khao Soi is the room's other flagship, stir-fried noodles tossed with chicken, braised pork, and the restaurant's secret sauce in a yakisoba-inspired preparation that you won't find at most khao soi shops in the city. For a traditional read, the Classic Chicken Khao Soi sticks to the northern template with chicken, pickled mustard greens, shallots, lime, and crispy noodles on top. On the side, Fried Marinated Pork Neck arrives in chili-roasted, bite-sized pieces and works well as a sharing plate before the noodles land.
Khao-Soi Soi Convent Silom sits at 14/2-3 Convent Road in Si Lom, a short walk from BTS Sala Daeng and MRT Silom. Convent Road runs between Silom and Sathorn, so the shop is easy to fold into a lunch break from the nearby office towers or a pre-dinner stop before heading further into Silom.
