The story
One of London’s most loved sushi and Japanese restaurants, SUMI is the younger sibling of Endo Kazutoshi’s Michelin-starred Endo at the Rotunda. Named after Endo’s mother, the restaurant brings the sushi master’s vision to a relaxed neighbourhood setting on Westbourne Grove. It is elegant and refined, yet warm and casual—a place where precision meets comfort. Executive Chef Christian Onia leads the kitchen, translating Endo’s signature style into a menu that honours Japanese traditions while drawing on the many influences that have shaped Endo’s journey.
The food at SUMI is described as an authentic taste of Japan, elevated and innovative. The thoughtfully pared-back menu focuses on quality and balance: handmade sushi and sashimi made with the finest seasonal ingredients, alongside robata grills and traditional Japanese Gohans. Drinks follow the same philosophy—a curated selection of sake, Japanese whisky, and cocktails that blend classic craftsmanship with a modern twist. For lighter afternoons, the Terrace menu (Thursday to Sunday, 3–5pm) offers favourites like temakis and nibbles, served outdoors.
SUMI is open seven days a week for lunch and dinner, with an inviting atmosphere that feels both refined and accessible. It has earned a Michelin Recommendation, a testament to the consistent quality and care that defines this Japanese restaurant. Whether you’re stopping by for a casual lunch or an evening of carefully crafted sushi, SUMI delivers a distinctly London take on Japanese dining.

History
If you hanker after top-quality sushi while waiting to secure a reservation at the ever-so-hard-to-book Endo at the Rotunda, a worthy alternative is Sumi in Notting Hill – less choreographed than its more illustrious sibling but serving dishes that are much more than outtakes. Housed in a bright, convivial space in an affluent neighbourhood, the dining room has been reconfigured since our last visit – the seating has been increased and the room unfussily decorated with pale wood and grey banquettes, while cooking takes place in an open kitchen to one side. Outdoor tables under parasols are also worth knowing about when the sun shines. Instead of Endo's highly personalised omakase, Sumi's diners get to choose from a carte, which is neatly divided into starters, sashimi, nigiri, temaki rolls, robata grills and gohan rice bowls. On the evidence of our latest visit, new head chef Christian Onia seems to be getting most things right: a garden salad (10 different vegetables brought to life by a wasabi wafu dressing) had a perfect balance of crunch and sweetness, while the robata grill helped to magnify the delicate nutty flavour of an Ibérico 'secreto' cut of pork, invigorated by the gentle heat of a yuzu kosho dressing. However, top-quality raw fish is the lynchpin here, from nigiri of rich chutoro (medium fatty tuna) or silky sea bass to fabulous temaki hand-rolls – say soft, creamy diced scallop with shiso flowers and soy. Staff are enthusiastic, and the drinks list runs from exotic cocktails and sake to some 18 wines (from £35), all of which are available by the glass (from £9).
