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!
Urchin is a fun one. Small, loud, big energy, and the fish is properly fresh. Nnigiri comes tight, rice seasoned right, knife work clean.
Book early and try not to sit by the entrance since the vibe drops there. Pricey, yes, but if you’re into Japanese with a bit of twist, it delivers.
A truly magical and unforgettable experience. I got tickets for Tuna Fight Club as an early birthday to my hisband and he was beyond happy and impressed, so was I.
The whole experience is fantastic: from the moment the tuna arrives directly from Heathrow, to the dedication and storytelling of everyone working here. I very look forward to visit the other restaurants of the Group or to come back to tuna fight club for a special ocassion. Thank you so so much to all the team but specially Felix and Camilo!
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.
