My friend and I went there last night for the second time. The food cannot be faulted as far as I'm concerned. It was delicious and authentic.
The service is excellent, the waitresses are joyful, sweet and helpful. I don't actually eat fish, so my options were limited, but the list of seafood Maki, Nigir, and sushi rolls was extensive. I had the chicken Yakitori, which is amazing, tender and exquisite and the Fried eggplant with sweet miso, which was unusual and scrummy! The Sake is delightful too, I recommend the Akitabare.
The food presentation is gorgeous, a feast for the eyes indeed!
The only possibly problematic thing is the price. You can leave the restaurant adequately fed and with a glass of sake for around £15, (my friend) but I managa to order a similar amount of food and spend closer to £25. That's not in my everyday food budget, but its a perfect place for a dinner with friends, share a bottle of sake, and enjoy the atmosphere.
Sake: £5.50/120ml glass ; £32/bottle
