Review Sushiya Cornerstone - London

This has been one of my go-to sushi spots downtown for over 5 years. Their sashimi boxes are excellent value, fish is always incredibly fresh, sashimi is cut thick. Service is exceptional and pretty quick for dine-in and take-out.

The only place we get sushi. Very kind family runs the business. Emphasis on quality over quantity (which, if you've only ever done "all you can eat" sushi you're in for a treat). Prices are also very reasonable - good value overall. They are good at making gluten free orders. I appreciate most sushi is gluten free naturally; but they take care not to mix the crispy bits of tempura or any soy sauce. I have celiac and have never been sick. They even give me a separate container of naturally gluten free Tamari with my take out instead of soy sauce. They'll also do the spicy salmon sans crispy if you ask.

This is the best Japanese restaurant I’ve ever been to! Authentic fresh food and a cute + cozy atmosphere. Both my husband and I loved the experience. We will 100% be returning when in town!

Lovely little sushi spot! There's a doorbell to dine in, they do want reservations as they only have a few spots for in-door seating. The teriyaki we chose was shrimp and beef. I enjoyed the twist that it's fried! I finished the rice faster than the main dish though. The combo was a good choice, as it gave us a taste of both dishes. I'm definitely gonna come back to try their other many sushi. Also to add, they had really great miso - was authentic didn't just taste like base.

I got the chicken teriyaki don - with the spicy mayo - Incredible food! Excellent, efficient service and high quality ingredients. I was welcomed warmly and will definitely be back!

Excellent sushi. Had a sushi box to go, very good quality and quantity for the price. Fast service.

The restaurant hop in the pursuit of decent sushi took my friend and I to Sushi Ya. Every time I've walked down Clarence, I've wanted to eat here, so the opportunity arose after starting the evening with bad sushi elsewhere. What a charming place. Its cozy and lined with a mirror wall to make it brighter inside. After checking the menu, our server started with a plate of edaname, followed by a not too salty miso soup that contained small cubes of tofu and finely sliced green onions. These dishes by the way weren't something we had ordered, they were included as part of the meal! Our medium sushi/sashimi pate followed after not too long of a wait. A rose was added to the plate in a nest of radish and carrot...beautiful presentation! The cuts of fish were fresh and of a decent sized portion and all the sushi was beautifully uniform. Wasabi was paired with a sweet rather than salty soy sauce which was a delightful and unexpected taste surprise which I loved. My friend had a hot pot of tea and I had a glass of water which was refilled when needed...our server was attentive, yet unobtrusive. Another family came in and sat behind us. They ordered different types of Bento boxes, so the next time we go, I'm going to give that a try. The chef and the server are a couple, so this is a family-owned and operated business. If you are seeking fresh, well-prepared Japanese food in a clean and quiet atmosphere, Sushi Ya won't disappoint! Sushi Yeah! and Sushi Yaaayyy! 😋❤🍣 I WILL be back many times and make sure to sample their very extensive menu. Thank-you for making my friend's last good meal in London (he's moving) enjoyable and memorable!

Got a lunch here, got the chicken Bento box and it was phenomenal. Definitely great people here, nice and friendly, great food.

Awesome restaurant. Delicious and affordable food. It is a very homey family restaurant with amazing service 😍 Will definitely come back over and over again 😊

Cozy atmosphere with amazing service and top-notch sushi.

Really fresh and excellent tasting sushi. Specialty rolls like dragon rolls are around $12 and regular rolls like spicy salmon around $6.

One of the best sushi experience I've had. The place is well maintained. Impressed with how well the kitchen and restaurant is arranged.

Dropped in lunch on Thursday, excellent! Quaint little place, excellent service and atmosphere. Tiny yet perfect! The kitchen, dining and excellent all in ONE. Service was wonderful. We have a chicken and a shrimp box lunch….delicious! Thanks.

Very authentic. Food is great and even the restaurant layout reminds me of places in japan ive been to. Just know its a small place so cant fit big parties of people.

Sushi Ya is one of those places that makes you feel like you are in another country. It's a small hole in the wall restaurant that feels like it's in Japan. The food is exceptional and probably the best in the city.

Tried the Chicken Teriyaki don meal and a couple of salmon sushi. It was a good meal for me.

Delicious fresh food, fair prices and smiling chef and staff :)

Cute little dine in place for a lunch. Fresh and delicious
