For anyone who has eaten at Nobu Matsuhisa's other restaurants in London and abroad, the food here will hold few surprises. It's the same phenomenally good - and phenomenally expensive (note the unprecedented 15% service charge) - Japanese-Peruvian fusion that's won the chain A-list fans from LA to Tokyo - the black cod in miso, the Wagyu beef, the sashimi with jalapenos, not to mention its blissful cocktails. While both London outposts now boast one Michelin star, the David Collins-designed Nobu Berkeley has a more youthful vibe than its older, calmer sibling Nobu London (19 Old Park Lane; 020 7447 4747), or perhaps that's just a higher incidence of plastic surgery? Diners congregate in the downstairs bar, where drinks are served by Amazonian waitresses; upstairs, there's seating for 200, as well as a separate hibachi table and sushi bar. It should be desperately glamorous, but at times the bare wooden tables, Euro-lounge music and raucous crowd apparently desperate to be noticed, make it seem more like an upmarket canteen. Still, judging by the number of flashy cars parked outside, the capital's bright young things aren't going to let the decibel level get in the way of a good time.
