Sushi Tetsu

Japanese aficionados make pilgrimages to this tiny Clerkenwell bar, where chef-owner Toru Takahashi, who apprenticed in Kobe and is an alumnus of Nobu, and his wife serve only ultra-high-quality sushi to a maximum of seven diners at a time. A la carte is available, although the chef’s choice omakase menu, a never-ending procession of buttery sashimi and perfect nigiri, is advised. This is one of the most difficult reservations to secure in London, but it’s worth spending the time trying to nail down a seat at the counter.
