Cubé is a new sushi counter and restaurant in Mayfair that does a serious £75 omakase at dinner. As well as the omakase (which you have to book for), there are a few sushi and sashimi sets on the menu for £25 or less, and the quality’s great for the price. It’s definitely worth checking out after work, and there’s also a low-key whisky/sake bar in the basement if you fancy a quiet drink.
