This spot is great! They have unique rolls most Sushi spots don’t have. I came from Scarborough just to try them out since my old spot closed down and I was unable to find similar roles anywhere else until today! I ordered the Ajax Special Roll and Deep Fried California roll and they were really good! I’m glad to say I found a new favourite sushi spot! Lots of options at a great price! Definitely worth checking out

Food was hot and fresh. Large chunks of fish and veg in sushi. Tempura was crisp and not soggy. Very tasty. Service was efficient and nice. Dining room was a little chilly at times due to the door opening right into the dining room. Can appreciate attempts to refurbish the dining room. Was nice and clean. Wouldn’t hesitate to come back.

This sushi made a grown man cry! We stopped in Ajax on our way through and found this little gem. What Umi sushi lacks in ambiance, it makes up for in flavor and quality. We loved the fries and my husband literally cried over the flavor and quality of the red snapper. We loved the food so much that we stopped in on our return trip a few weeks later. We look forward to a future return visit. The crew that works there was also very friendly. 1000% recommend.

I’ve visited Umi Sushi in Ajax a few times now—both for dine-in and takeout—and it never disappoints. A couple of months ago, my partner and I dined in and tried the Maki Party Tray (58 pieces, $51.50). We enjoyed it so much that we ended up ordering the same tray again for takeout not long after. The tray offers a great mix of rolls: 6 pieces each of California, salmon avocado, spicy crab, spicy salmon, avocado cucumber, tuna, and salmon rolls, along with 8 pieces each of the dynamite and rainbow rolls. Everything was incredibly fresh and flavourful. One thing I really appreciate is the portion size—it’s genuinely enough for two people, which isn’t always the case at other sushi spots. The value for the price is fantastic, and Umi Sushi has definitely become one of our favourite go-to places in Ajax.

This restaurant is exceptionally clean, and the food is absolutely delicious. The owner is incredibly warm and welcoming. She even took the time to recommend dishes based on our personal preferences, which made our dining experience all the more enjoyable. What truly touched us the most was when I accidentally left my Louis Vuitton wallet at the restaurant. The owner not only found it, but also went out of her way to verify my identity and personally return it to me. She doesn’t just run a wonderful business—she also has a truly beautiful heart.

Their system in terms of ordering through our website is so efficient and very simple for individuals who are not the most tech savvy. Upon arrival, all the food was prepared with span of 10-15 minutes. The renovated the restaurant as of Nov 2024. Amazing service! One thing I’ll say is they are on the expensive side, but they truly know their worth.

I’ve been going to this location for over a year now however I’ve decided to add a review since they’ve newly renovated their establishment. Gone are the old remnants of a prior fish n’ chip joint that Umi Sushi took over and in its place is a beautifully designed and decorated restaurant. A decorated restaurant is only as good as its food and its service and here is where Umi Sushi excels. Their sushi is delicious and full of flavour, as well as a visual treat. I recommend trying the house special roll and I won’t say any more than that. Since the renovation, Umi has gone All-You-Can-Eat for a modest price and the quality does not suffer. You can also go all in All-You-Can-Drink for an extra cost but I wasn’t that daring. However, while the food and service are excellent, the dining experience is not as immersive due to the bright lighting and the weird selection of a Top 40 music radio station for ambiance. Something softer in both departments would go a long way. Also noted are the construction/cleaning supplies in the hallway leading to the bathroom. Perhaps these are leftover from the renovation but cleaning this up and putting your focus towards renovating the bathrooms would elevate this restaurant to the next level. Lastly the menus need a look over as I found a few spelling mistakes. Attention to detail is important if you’re making sushi. Good luck! I wish you the best and I will be back!
