⚠️ Risks & cross-contamination
- The kitchen is not dedicated gluten-free, so cross-contamination risk exists.
- Fryers are not dedicated to gluten-free items, limiting safe fry options.
- Some staff are reported to double-check allergens and communicate with the kitchen, which reduces risk when engaged actively.
- Individual toppings and sauces may vary in gluten-free status; verify with the server for each item.
