Best sushi and fusion food in London! It’s such a lovely place with super fresh food. It is a bit pricey, but definitely worth it once in a while. My partner and I have been here twice and both times the food was amazing. They also have a great selection of wines and drinks, which we really enjoyed.
The only thing that disappointed us a little was the way the lady at the front desk spoke to us when we asked how to book for the famous Tuna Fight. We just wanted to know how to get our names on the list.
The toilets are okay, but you do have to walk past the kitchen to get there, which feels a bit odd for a restaurant like this.
Overall, the food is 10/10 and it’s great to see such fresh tuna being served in London! Hopefully we’ll manage to book and come back next year for Tuna Fight Night — I’m sure it won’t disappoint!
A special night for us celebrating our one year engagement, staff were great, friendly, and attentive - served by Rob H.
All of the food was fantastic, my favourite was the Pigeon Karaage, and my partner loved the Tuna Tartare. The Japanese Black Sirloin was also really special.
Great food. Great atmosphere. We will be back.
Arigato Gozaimasu!

Food is great, with deep flavors and interesting pairings. Sushi is very fresh and well prepared. However, atmosphere is odd for a 100£ pp location. Chefs counter is great, but if you are sitting in the other half of the restaurant near the entrance the vibe is a bit odd.
Was really looking forward to this dinner and they didn’t disappoint. Food is great, service is very good and the staff are attentive and very accommodating. We ordered too much and had to cancel the nigiris cause we were just so full. Brilliant place! I would highly recommend. Will probably concentrate on nigiri next time I’m over. Thanks for having us!
A truly unforgettable experience. Many months of waiting later and the day came to attend Tuna Fight Club! If you can secure a booking for this event, it is truly something out of this world. The freshness of eating fresh Tuna scraped off the bone in front of you is once in a lifetime. For the price/value and the flavour this was a 10/10 and the team are all lovely helpful and knowledgeable. True love for sushi. Keep fighting!
