Thrashing guitars? Hip young staff? Tattooed chefs? Must be the latest Japanese restaurant. In the last 18 months thing have got a whole lot louder and cooler on the Japanese dining scene in London. The flavours are bold, the presentation simple, and the staff look more like art school dropouts than the serene serving staff you used to find in London’s Japanese restaurants. In the same ilk as rock ‘n’ roll ramen-meister Ross Shonhan’s venues Bone Daddies and Flesh & Buns, Kurobuta is more New York than downtown Tokyo. But, is the food at this upmarket isakaya (Japanese pub) good enough for a rock god, or not even fit for the hounds of hell?
