This place has the usual fare for a sushi restaurant, but better than average.
The sushi rice is gluten-free, meaning they don't add any gluten-containing sauces to it by default. (Some sushi places do.)
You can specify "gluten-free" when you order. As far as I can tell, this means they will make sure not to top your sushi with any unmentioned gluten-containing sauces, they will put it on a container or plate separate from any sushi with gluten, and they will give you a container of gluten-free tamari rather than the usual shoyu packets. The tamari is unlabeled, but I've eaten it and had no symptoms.
My favorite sushi rolls are the yellowtail scallion and the rather unique AAC (avocado, asparagus, & cucumber).
