A quick glance at the website is essential before a visit to the tiny Sushi Tetsu as the chances are it may be may be fully booked. Still, once you’ve secured a perch and made it through the door, you’ll see a handful of punters, with chef/proprietor Toru Takahashi on the other side of the counter, calmly preparing the sushi and sashimi with near forensic precision. This is a husband-and-wife outfit, with spouse Harumi completing the perfect circle that is Sushi Tetsu. Since you’ve gone to all the trouble of bagging a seat, you might consider going for the bespoke ‘omakase’ menu at 96 quid a pop: what you get depends on what the chef decides is good enough, so glistening sea urchin, turbot, snow crab, black bream, octopus and (hopefully) seared otoro fatty tuna might be on the cards, all embellished with the necessary accoutrements (wasabi, soy, mirin, seaweed and chilli). From the rice to the saké, everything is impeccable.
