★★★★★ 5.0 Lynn Jiang · Feb 2026

We tried Sumo and had a great experience! The nigiri was beautifully presented and very fresh. The signature rolls were delicious and well-balanced. We also ordered the teriyaki salmon and steak — salmon was great, and the steak was good quality (just a bit overcooked for our preference). The fried udon was tasty and comforting. The décor is cute and very clean with a bright, modern vibe. Great value for the price — we left so full and will definitely be back!

The food was well worth the wait. We ordered the sushi appetizers, stir-fried udon, sashimi, salmon skin hand roll, and the Sumo roll. We enjoyed everything and will definitely be back!

I had an amazing experience at Sumo Sushi. The food was fresh, flavorful, and came out quickly, but what really stood out was the service. Our server went above and beyond even though he was juggling everything at once — bussing tables, running food, taking orders, making recommendations, and even helping prepare dishes. Despite all that, he stayed patient, friendly, and incredibly accommodating the entire time. It’s rare to see someone handle that much with such professionalism, and it made the whole meal feel even better. Definitely one of the best dining experiences I’ve had in STL.
