You need to call them you're asking the local guides.
I don't know about gluten free menu but I just had those fish tacos a week ago and they are pretty good. I'm sure they could throw them in corn tortillas for you.
I don't know about a gluten free menu per se but they do have corn tortillas and gluten free buns available now.
I think a faster and more accurate answer would be to call them and ask. Or you could use lettuce wraps.
