MOD Pizza offers a gluten-friendly crust and a cauliflower crust. From the chain's own FAQ onward, the company makes clear that all items are prepared on one serving line with shared ovens, surfaces, and utensils, so cross-contamination is a real risk. The chain does not recommend its crusts for coeliacs. Diners who choose to try it can ask staff to use fresh gloves, clean tools, and a wiped-down prep area, and can consider having the pizza baked on clean foil. The simple act of ordering a gluten-friendly crust puts the order at a "best effort" level. Kitchen practice varies by location and shift.
Honest caveat, The chain's own FAQ states 'none of our crust options are recommended for those with a gluten sensitivity' and multiple independent reviews confirm shared prep and ovens introduce significant cross-contamination risk.
