I noted in my Resy reservation that a guest is celiac. The restaurant called me in advance to walk thru options and notes server can also assist.
I ordered a burger with the GF bun and side salad. (They did put the fried onion strings on the side in a little bowl which I just moved off my plate although order stated not to include.)
Felt comfortable with options and service.
