"Sachi is a Japanese restaurant set within the impressive, 1200-square-foot Pantechnicon building in Belgravia. It can feel serious at first, but once you’re seated, it’s a smooth succession of beautifully presented tuna usuzukuri followed by salmon sashimi that’s so gorgeously plated it could have its own social media following. This is a very cool, low-key sushi spot that should be on everyone's radar, but we’re kind of happy it’s not. The rooftop has a shorter version of the same menu, in a more loungey-bar-like room." - heidi lauth beasley, rianne shlebak, jake missing
