Zuma in Knightsbridge is an achingly cool fusion Japanese restaurant offering a sophisticated twist on traditional izakaya informal dining. To make the most of it, order a bunch of dishes to share and let the kitchen decide what's the best order to eat them in. This is an up tempo affair; the music will be loud, the place will be busy and the ambience excellent. But the food is no afterthought. The sashimi will melt in your mouth and the flavours of the wagyu beef will linger. The decor is stylish with a variety of seating options, from the vibrant main open plan kitchen and dining area to one of the two quieter sunken kotatsu dining rooms.
