Chains are more predictable than independents, and that predictability cuts both ways. What to ask, what almost always fails, and why a published allergen menu is not the same as a safe kitchen.
A chain's allergen menu tells you about recipes. It tells you nothing about the fryer or the prep surface in the location you are standing in. Testing studies have repeatedly found detectable gluten in restaurant food ordered as gluten free, concentrated overwhelmingly in pizza and pasta. The ingredients are consistent across a chain. The kitchen is not, and it varies store by store.
Point CiCi at the barcode on anything on this list and get this same reasoning in about two seconds, plus the carbs and whether it has been recalled. 360,000+ packaged foods are already read and waiting.
Each guide covers a whole aisle and explains the mechanism, which is more portable than any list of names.
This site answers the question you knew to ask. The app answers the one you didn't: the barley malt in a rice cereal, the wheat starch in a gummy. Scan the barcode, or photograph the panel when the barcode isn't in any database, and CiCi shows which words on the label produced the answer.
14 days free, then $29.99 a year. Cheaper than Fig, and it does what three separate apps do. This website stays free forever either way: every answer on it, permanently, with no account.
