Stumbled across this place on my way to Nic Rascle's excellent fish shop on Robert Street (between Hampstead Road and Albany Street). I liked the look of the place from outside and was amused by the juxtaposition with one of London's best-known subcontinental enclaves.
Turned out to be a winner. Very compact (9 seats, 3 at a small sushi counter and 6 at the window counter), menu more or or less all sushi + sashimi + rolls with a few sundries. I ordered a lunchtime sushi set (4 x nigiri, 2 x California roll, 2 x oshi-zushi, miso soup) @ £9.50 plus one piece of scallop sushi @ £2.40. All tasted good and the scallop was reminiscent of Tomoe's, sweet, succulent and moreish. Superior touches like using proper crab meat rather than surimi in the Calif rolls. Got chatting to the owner Hitomi, a 1st time restaurateur whose husband is a chef at Umu. Lovely lady, I wish her and her business well although I'm not convinced that the location is the best. Through her husband's connections, she is able to access better quality fish from Atari Ya, the distributor that supplies fish to most of London's better Japanese eateries, that explains the quality of the fish/seafood especially the scallop.
Shiori is the Japanese word for "bookmark" and rather than business cards, she hands out bookmarks with relevant restaurant info to customers, a cute touch.
