A true hidden gem I cannot recommend my friends and family enough. They essentially supply very good quality sashimi grade fish in the UK, and they have several restaurants that serves top-notch quality sashimi too. Check out their website here.
We went to the one in town behind Selfridges b/c it’s the most convenient one. It’s a takeaway shop, unlike their other restaurants. It has a bar where sushi is prepared and served, and a few tables about 3-4 indoors, and about 3 outdoors too. They also serve a good range of Japanese drinks and side dishes!
This bowl we had was their Super De Lux Chirashi Don for about 20+pounds.
