If you've ever thought, hey, someone should open a serious sushi restaurant inside a Georgian townhouse, you'll find exactly that at Dinings. A dedicated sushi counter’s been shoehorned inside what would be the hallway, and there’s a pokey sit-down restaurant downstairs. It isn’t the most comfortable place to sit, but it’s worth the trouble for some of London’s best sushi, which does both classics and new-school dishes very well. The lunchtime sushi sets and chirashi are a great deal, as you’ll find the best stuff - even o-toro - mixed in there for the relative bargain of £25. For dinner, Dinings is definitely one for the sushi enthusiasts, as a serious bill can rack up very, very quickly.
