Amazing! Hands down the best sushi I've had in Durham region, and I think you'd be hard pressed to find a better place in Toronto. Definitely go for the dine in experience. Presentation is amazing and service is just as good. Will definitely be back. Sushi is so soft, melts in your mouth.

Amazing quality food! Came here with my sons and ordered a lot of dishes. Everything was very fresh and tasty. I really enjoyed the seared tuna which came with a small arugula salad, so refreshing! I had the fish cake soup and it was very flavourful and savoury. The rolls were wrapped tightly and sashmi very fresh. I am looking forward to coming back again soon.

Amazing food and service! My favourites were the pressed torched sushi and bulgogi poutine. The sashimi sampler was also very fresh.

Solid spot for Japanese eats — we were more than pleasantly surprised when we came here on a whim for a quick meal before a multi-hour drive. We sat outside in the patio and ordered a few dishes, my personal favorite being the butter squid. The quality of the ingredients were excellent. Highly recommended for anyone in the area.

This is one of the better Japanese spots in the Ajax area. Good quality sushi and tapas dishes. Fair prices for the rolls but the tapas menu is a bit pricey for the quantity you get. Still really good though. Service for dine in was great.

You can expect a great variety of sushi & other Japanese dishes / appetizers. I will be returning very soon because I’m already craving it again. Highly recommend!!!!

Pleasantly surprised by the quality of the sushi here from such an unassuming place. Loved the options for their special rolls, the sauce on the maki are so good! Service is a little slow but the workers are very friendly. Dishes are on the pricier side but you pay for the quality.

Was just okay. The customer service is fantastic and food is fresh. We went to visit after seeing all the great reviews. They have loads of variety including torched sushi and poke bowls...both of which we tried. Torched salmon was good, didn't love the poke bowl, was a little heavy with the sauce on top and a bit dry? The rice on some of the rolls didn't seem as fresh as others. We did go on a random Wednesday night and I wonder if that had something to do with the inconsistency with food. Also the interior needs a bit of work. Was not the best sushi we've had but nice location and the service was great!

Best sushi I've had in the Durham region, you'll never go to another AYCE place again. Great staff and quick service. The Spicy Kani Roll and Black Dragon rolls are a must try.

My new favorite sushi place in Ajax!! And it is also an Izakaya! The menu is really good and the staff is super nice! Everything I have ordered is sooo good! You are getting really high quality sushi compared to a lot of places in the East GTA area. I have been here more than 10 times and I have not been disappointed!! I highly recommend!
