I was glad that I went to this location for my first time at Sushi Ai. My partner went to the one in Clayton and Maryland Height before, but he liked this location more, in term of the quality and variety. Sushi here was decent. liked the American dream and Maryland rolls the most. Price is relatively cheap $14.99 for lunch, and $23.99 for dinner AYCE sushi. Good ambiance and fantastic service.
Good go to place to enjoy sushi and basic japanese food! Pics are of Salmon Bento box and Shrimp Ramen noodle soup.
Sushi Ai is always our favorite!!!! In my own personal opinion, I think St Charles is the best location! We love all the decorations, the attentive workers & the delicious all you can eat fresh sushi! I always end up eating way too much but it’s always worth it in the end!!! We travel 2 hours just for this place!!
We LOVE this place! The all you can eat option is a great value. The food is high quality and generous on the fish to rice ratio, but what really makes this place is the service. They are just amazing people who go the extra mile to make sure you are having a good experience. A must go if you are in the area.
2025— Many tasty options. Sharing latest menu here. (Their website menu was crashing.). Skip the Boston roll, it is not crab. It is “Krab.”
Thursday early lunch is great, no wait and not crowded! $15 all you can eat for lunch is such a great deal. Sushi is excellent! You can ask for "hand roll" by writing next to the sushi rolls selected. Dinner is $20.
For $23.99, you get 2hrs of all you can sushi, and appetizers. I ate so much sushi and enjoyed all of it. The sushi quality for an "all you can it" is really good. Service feels a little on the slower side, but they were nice and cooperative. The decore was nice. They had fake bamboo trees that were pretty and you can see the chefs on the front desk make the sushi which was pretty exciting. Their bathroom door window was cracked, and hope gets fixed soon cause it doesn't look pretty. Overall, very delicious experience, well worth the price and would come again.
Great service. Good vibe. Almost a bit crowdy but its manageable. That is the Hawaiian roll pictured here. It was delicious but definitely on the sweater side. The price is pretty decent!
