Edited to add: I went back the following week and had a way better experience, better service, and discovered there IS tamari (gluten free soy sauce) available. The manager, Ricky, was extremely helpful and accommodating. You gained an extra star. ⭐
The lunchtime buffet is a really good deal. The sushi was fresh and delicious. Our server was pleasant enough but in spite of it saying on the menu "ask your server if you have any food allergies" he seemed utterly lost when I asked. I had to persuade him to ask a manager. We also had to wait a LONG time for our food. Some more training in good customer service would be beneficial.
