Nobu is a global phenomenon, and one which has redefined Japanese cuisine across a couple of oceans. It's controversial (their two London loncation were stripped of their Michelin stars in 2014, for reasons which are still kind of unclear) but relentlessly glamorous; it's still a safe bet for spotting A-listers and finding the beating pulse of Mayfair after dark. If that's your thing. We recommend the razor clam Tiradito for £16, or the lobster tempura with yuzu truffle and spicy lemon garlic for (sadly, a whopping) £45. No doubt about it: Nobu is still defining Sloanie elegance, and if you're after high-end Japanese fair, it truly can't be missed.
