A tiny, 10-seater Japanese restaurant where husband and wife chefs serve a no-choice “omakase” menu opens in Mayfair tomorrow. Roji is the first venture from the couple, Tomoko Hasegawa and Tamas Naszai, who met while working at another Japanese restaurant, Tokemiete.

Roji means alley, appropriately for a restaurant that is tucked away in a courtyard off South Molton Street. The menu will be dominated by fish sourced from Cornwall, including a sushi course, alongside vegetables from Sussex specialist Nama Yasai, accompanied by sake or wine.

For both chefs the launch marks their debut in charge, although each has a strong CV. Tomoko worked in top kitchens in Tokyo and Paris before coming to London, and Tamas is a two-time winner in the Japanese Culinary Art competition.   

Evening sittings are at 6.30 and 8pm, and meals must be paid for in advance. Lunch slots will be available later in the year.

Roji is backed by the people behind Japanese restaurants Chisou in Mayfair and Sushi Atelier in Great Portland Street.
