dd4 has egg, milk, and peanut allergies, and has been given an epipen.
i knoew macdonalds were good for listing allergens, and there half a dozen or so items that dd4 can actually have, though she may get fed up of fish fingers when she is older.
where else lists things well? when i have asked before if they could find out if things were cooked in butter or oil, or milk added, when out and about i get a lot of blank looks and 'i dunno'
