I've eaten here several times, never had any issues. They have a great selection to choose from. Not all staff is gluten knowable but when they aren't sure, they'll ask someone who knows.
Yes
They said most Chinese, Thai, Korean, and sushi can be made gluten free. They made sure to label the containers.
They try very hard! I enjoy their food, but as a Celiac, I have gotten mildly cross contaminated before.
No
Very friendly. They know which items you can eat. Delicious! Try the Bi Bim Bap!
