I always order take out, so haven't experienced the service issues, though I have ward about them. I love that there are so many GF options. Please note that those menu items that are indicated GF still have to be requested as such. In other words, the GF indication means they can make it GF for you, if you request it. If you don't explicitly request GF, your item may be prepared using gluten.
Sushi is decent. Service is never good and it always takes forever to get your food.
Gluten free sushi menu and they have tamari. I eaten here a few times and loved it every single time.
