⚠️ Risks & cross-contamination
- The establishment is not a dedicated gluten-free facility, so cross-contamination risk can never be fully eliminated.
- While gluten-free buns and GF fryers are common, there is no formal, public guarantee of zero cross-contact.
- Bun availability for some items (e.g., hot dogs) has changed over time; confirm bun choices when ordering.
- Staff knowledge about safe GF options is mentioned in recent experiences, but no formal certification is noted in the collected information.
