Zuma may now be a global brand, but this long-standing Knightsbridge restaurant was the originator of its informal, izakaya-inspired Japanese cuisine. Managing to still feel fresh over 20 years after opening, its home to a glamorous clientele who fit right in with the striking surroundings and bustling atmosphere. Sharing is a great way to experience as much of the extensive menu as possible – but if you have to prioritise, make sure you try the array of produce cooked on the robata grill, from tofu to chicken wings.
