A community forum thread from 2006/2012 on celiac.com reports that gluten-free treats were available at a Crown Bakery in Worcester, MA, but the most recent post is over a decade old and warns the information may be outdated. The official website for Crown Bakery Guam contains no allergen content. A different venue, Krown Bakery & Eatery in Minnesota, claims on its about page to offer gluten-free options but does not describe dedicated equipment or cross-contact protocols. No modernday, verifiable gluten-free practice is documented for any current Crown Bakery location. Call ahead to confirm if any gluten-free offerings still exist and what the cross-contact risk is.
Honest caveat, No current, verifiable gluten-free practice is documented; the only community mention is over a decade old.
