I've been here a few times now; they have rice bowls that are can be made gluten free, and if you ask they will list the allergy to be more safe with it.
At the time of writing they use Temari in the KBBQ bulgogi bowl too, which is what I got. You can always double check with them, I've not gotten sick from it so far.
The food itself is tasty, if slightly pricey for the portion size though. But totally worth it IMO, so hard to find GF KBBQ!
