Mayfair’s Sumosan was among our favourite London restaurants for high-end modern Japanese food, so we were sorry to hear it was closing. But this elegant reincarnation in 50 shades of grey (in partnership with Twiga in Monaco) hasn’t strayed far, either in location or ethos. The four-storey property has a sweeping staircase linking a basement nightclub, first-floor dining room and spacious top-floor bar. On the food front, Sumosan’s Japanese menu has been joined by Italian dishes, so you could follow sushi with sea bass spaghetti, Dover sole or veal Milanese. We stuck with the Orient, and were as impressed as ever: fleshy wasabi prawns, crunchy rice ‘pizza’ topped with spiced salmon, punchy rack of Devon lamb with mustard sauce, and our all-time favourite: T&T sushi rolls, heady with truffle-laced tuna. To drink, there’s a Euro wine list and one of London’s best saké selections. The restaurant now offers a daily lunch service (weekends too). Prices? Yes, they’re high.
