Review of Subway

They carry Gluten Free bread. You can check the Subway website to see that almost all subs, with the exception of the meatball and maybe 1 other can be gluten free with the gf bread. They usually ask if it is for diet or allergy. They will change gloves and take precautions. There is a $1 charge for the GF bread. Last I checked, GF bread is not offered at any Longview locations, but I have not asked in a long time. // In October 2018, they left their location and built a new building right down the street. They still carry GF bread.

Celiac friendly?

Yes
