What you can eat here
Pulled from Gluto's celiac safety report for this location.
✅ Reported safe options
- Hook and Ladder sub on gluten-free bun (Schar)
- Italian sub on gluten-free bun (Schar)
- Any sandwich on a gluten-free Schär bun, when prepared with proper precautions (glove changes, separate prep, and foil in the toaster)
⚠️ Risks & cross-contamination
- The facility is not dedicated gluten-free, so cross-contact risk cannot be ruled out entirely.
- Cross-contamination remains possible if gloves aren’t changed consistently, utensils aren’t reserved for GF prep, or prep areas are not kept separate.
- Some instances note temporary shortages of gluten-free bread, which can affect availability and planning for a meal.
- To minimize risk, diners should communicate clearly about allergy needs, confirm gluten-free handling steps (glove changes, separate prep surfaces, foil-wrapped toasting, and labeled orders), and verify current bread availability at the location.
