We came here for roll with friends and everything was absolutely delicious. The staff took great care of us, answered all our questions patiently, and even surprised us with a complimentary dessert The service was warm and attentive. We had a wonderful experience and will definitely come back!

I honestly did like the sushi train experience, it was very cute and all the families with kids loved it. But we had an allergen experience that really soured the dinner.
If you have nut allergies be careful of the sushi train!! They don’t mark or label anything that has nuts in it, or have any warning signs that their sushi may contain nuts.
Our server didn’t ask about allergens, nor did we think a sushi place would be where we’d worry about nuts in the rolls. My husband is allergic to nuts, and picked a plate that looked very similar to their caterpillar roll with avocado on top and eel in the middle. As soon as he bit into it he had a feeling so he immediately spit it out. When we brought this up to our server, he admonished my husband for not knowing better. He said “it’s clearly listed in the menu that we have walnut shrimp rolls and didn’t you feel it crunch when you bit into it?”
We get that it’s on the menu, hence why we didn’t order it. But none of the train plates are labeled nor is there a sign that says to look out for rolls on the train that may contain nuts. Beyond that, they comped the walnut train plate (the one my husband bit and spit out) and offered to pay for Benadryl from the Costco.
For us, this could’ve landed us in the hospital since no allergens are labeled or warned about. And the response from staff shows that they are not allergen conscious. So unfortunately, we won’t be coming back.

Our new favorite sushi restaurant!
As people who try a lot of sushi restaurants, we were blown away by our experience at Sumo. We ordered many items, but there were two standouts that were truly unique and unlike anything I’ve had anywhere else:
• Agedashi Tofu: The texture was incredible—perfectly crispy on the outside while remaining silky and light on the inside. It’s a must-order!
• Tropical Mango Roll: This was a total showstopper. The combination of fresh mango with the savory elements of the roll (maguro and sake) was so refreshing and creative. It’s a flavor profile I haven’t found at other spots in the area.
Beyond the food, the hospitality and service were so kind and welcoming. You can tell they really care about their guests. The ambience is also fantastic—it has such a vibrant, high-end feel that makes for an incredible dining experience.
If you’re in Los Altos, don’t miss this gem. We will definitely be back!

Although it doesn’t look fancy on the outside, this restaurant was such a lucky find for me and my family. Not only was there service incredibly fast, but the quality of their food blew me away too. My family loved their sushi and teriyaki sticks, saying that the meat was very tender. I’m vegetarian and their fake beef still makes my mouth water as I type this review. The servers were also very courteous and gave us complimentary ice cream at the end. Will definitely be back!

Sushi is legit! Staff is super friendly and attentive. I forgot the name of the roll I ordered but it’s the picture below. It was really tasty. The tempura veggies were delicious too. No boats though, but that doesn’t matter to me. I didn’t come for the boats. I don’t eat boats- I eat sushi.

I really enjoyed Sumo sushi. Very fresh and tasty fish, complimentary appetizer and dessert, and the sushi boats! What could be better? Agedashi tofu was tender and flavorful, hamachi avocado – refreshing, and the rolls and the nigiri just right. I shall be back!

My husband and I dined at the Sumo Japanese Restaurant in downtown Los Altos on a Thursday evening. It was the perfect way to wait for a tow truck to arrive due to my car’s flat tire! We ate indoors but there are a few outdoor tables. Spacious yet cozy we ate near the window as the hostess promptly served us tea. I ordered the Unagi Donburi (broiled eel with sauce, rice on the bottom and two slices of Takuan (pickled yellow radish) served in a traditional lacquered Unaju box & lid. The unagi was a bit mushy for my taste. My husband ordered a sashimi plate that was presented in a lovely glass bowl filled with ice. He said the sashimi was very fresh and delicate in flavor. Downtown Los Altos has many restaurants to choose from and it was pleasant to be greeted with hot green tea and smiles.
